Immortui

Immortui is a celestial whose power is fed by death and whose creations include vampires and the demon races of the Red Space. Sealed away after a conflict with the Ancient Ones, he works through worshippers, markings, hosts, and cross-plane openings before making Quinn Talen's power the key to a renewed escape. His final campaign makes him the principal enemy behind the demon war, although several accounts of his ancient history remain incomplete or disputed within the corpus. (Chapters 1356, 1937, 2310, 2369, and 2539–2540)

Biography

A dead god's influence on Earth

Immortui first enters the recorded story as an object of Laxmus's worship rather than as a physically present actor. On awakening, Laxmus adopts Immortui's name, calls him the being who gave vampires their power, and announces that killing humans will send souls to the “undead world.” Those statements establish the faith that later followers use to justify violence, but they are Laxmus's interpretation of Immortui's wishes; the scene does not show Immortui issuing the order himself. Later celestial observers confirm that Immortui claims influence over the region containing Earth and gains energy from its deaths, giving the cult's language a real connection to his condition without validating every detail of its theology. (Chapters 1356, 1714, and 1951)

Bliss later supplies the principal account of Immortui's ancient past. According to her, Richard Eno once opened a route to another plane, allowing Immortui to plant “seeds of power” on Earth from which vampires arose. She says his broader gift can transform living beings into many kinds of demons and that his condition—the event that supplies a celestial with power—is the loss of life. His pursuit of that condition brought him into conflict with other celestials and eventually required three Ancient Ones to seal him in another plane when they could not defeat him outright. Bliss admits that even celestials do not know whether the Ancient Ones were the first of their kind, and later Red Space traditions describe Immortui as having been sent into an already abandoned world; the exact chronology, motive for the transfer, and relationship between these versions are therefore unresolved rather than safely combinable into one history. (Chapters 1937 and 2368)

From confinement, Immortui cultivates agents able to advance his return. A mark on Zero allows direct mental communication, and Immortui acknowledges that Zero's killings have supplied enough souls for the next stage while ordering him to kill Erin, whose dhampir power is a threat to demons. Zero believes Immortui can restore people he lost and treats that belief as the other half of their bargain, but at this point the promise is Zero's understanding, not a demonstrated resurrection. The same campaign uses the Red Heart and Agent Four's magic circle to create a cross-plane breach. Immortui remains restricted from crossing it unaided, so a flesh-bodied emissary and other demons guard the opening while he forces against it from the far side. Those beings act on his instructions but are subordinate creatures, not alternate bodies of Immortui. (Chapters 1960, 1965, 1970–1976)

The breach brings Immortui into direct conflict with Mundus inside the Red Space. Immortui recognises that Mundus cannot defeat him and reads the messenger's resistance as an attempt to delay his passage; that delay nevertheless gives Quinn and Agent Four time to reverse the Earth-side circle. Quinn channels celestial energy received from a worldwide audience into the closing mechanism, while Immortui wounds Mundus and protests as the route collapses. The operation stops his immediate return but neither kills nor permanently weakens him. Its later significance is strategic: Quinn has now frustrated multiple attempts by the same imprisoned enemy, giving Immortui a personal reason to seek his power as well as a practical one. (Chapters 1983–1985)

Marks, hosts, and the Talen ultimatum

After a period in which Earth treats the first breach as a defeated crisis, Immortui renews his campaign through concealed markings. Magnus can place a temporary version of Immortui's mark on other vampires, whereas his own connection is permanent, letting a wider network remain hidden until activated. When Jared attacks Minny with strength beyond his ordinary level, the mark supplies celestial energy and suppresses his normal control. Immortui then speaks through Jared's glowing-eyed body. The narration and witnesses explicitly distinguish the channel from the victim: Jared is a host whose voice and actions are being taken over, not an incarnation or avatar that should be treated as Immortui's own body. (Chapters 1986 and 2307–2309)

Using that host, Immortui offers Quinn alliance. He argues that vampires originate in his power and that Quinn cannot fully sever the resulting link; because Quinn has grown beyond other vampires, Immortui wants him both to open a route out of confinement and to fight the Ancient Ones. He promises the possibility of recovering lost loved ones and claims that his demon armies have matured through the Red Space's constant fighting and death. Quinn refuses because Immortui's conflicts have already killed people he cared about. The rejection turns negotiation into a personal threat: Immortui declares that any marked person may become a weapon against Quinn's family, then forces Jared to cut his own throat to prove that Quinn cannot save everyone. (Chapter 2310)

Immortui follows the threat with dispersed attacks rather than meeting Quinn openly. Marked prisoners, guards, and other compromised vampires create emergencies around the settlement and Minny's school, forcing Quinn's allies to investigate people who can conceal the sign until it activates. The attackers are of uneven personal strength; the danger comes from surprise, coordination, temporary celestial reinforcement, and Immortui's ability to redirect attention. Quinn recognises that weak attackers are distractions while Magnus advances the real operation elsewhere. Jared's death and the uncertainty over who else is marked also change the conflict from a single duel into a security crisis in which normal social trust becomes a liability. (Chapters 2311–2317)

The campaign does not break Quinn into service as intended. It instead persuades him that killing Magnus or defending one location cannot end a threat able to operate through anyone. Quinn conceals his movements, leaves Peter impersonating him at the settlement, and begins hunting the portal project while trying to keep Immortui from learning where he is. This is the inverse of Immortui's ultimatum: the threat to the Talen family gives Quinn the motive to cross into the enemy's own plane, while Immortui's reliance on layers of agents prevents him from seeing that choice until the breach is already closing. (Chapters 2311, 2320, and 2356–2357)

Opening the road to the Red Space

Magnus's operation concentrates hundreds of vampires, crystals, ancient magic circles, and Jessica's dhampir capacity at a concealed Earth facility. The device drains the assembled vampires into Jessica, amplifies the gathered power, and uses it to force a route to the plane containing Immortui. Magnus describes the goal as creating an opening large and stable enough for Immortui to enter Earth. This is not a solitary spell cast by Immortui: his contribution is direction, demon reinforcements, and power granted to followers, while the Earth-side machinery, magic, captives, and willing collaborators supply the opening conditions. Jessica also observes that some participants retain their own personalities and choose to serve him, distinguishing willing followers from those whose bodies he directly controls. (Chapters 2346 and 2348)

Immortui responds to the opening by sending demon generals through and moving toward it with two of his strongest allies. He expects Quinn to defeat an ordinary general and treats the reinforcements primarily as a delaying action, showing that his objective is time rather than a conventional battlefield victory. Magnus meanwhile uses a transformed state powered by Immortui, but that form remains Magnus's borrowed enhancement, not evidence that Immortui has manifested through him. When Magnus is killed and Quinn destroys the regenerating general, Agent Four reverses the circle before the rift can become permanent. (Chapters 2350 and 2354–2356)

Quinn enters the shrinking portal by prior arrangement with Agent Four, leaving no time for companions to follow. His connection to Immortui's vampire power helps the Red Space accept him after initial resistance, while closing the path prevents the enemy army from immediately using the same route. Immortui experiences the closure from afar and first condemns his human and vampire agents as useful only for reproduction and death. The rage spreads his mist across nearby worlds strongly enough to generate destructive weather and environmental effects, demonstrating that his emotional response is coupled to power distributed through the plane rather than proving that the immense mist itself is a separate physical body. (Chapters 2356–2357 and 2369)

Learning that Quinn has entered the Red Space turns failure into a new opportunity. Immortui cannot initially locate him across an entire universe, and Quinn's arrival near the old Champions makes an immediate assault risky. He therefore orders that Quinn be captured and psychologically broken: Quinn's power might still open a route from inside, and a converted Quinn would be valuable against the Ancient Ones. This choice reveals the logic joining Immortui's two campaigns. He does not merely want passage; he wants a force strong enough to overturn the celestial hierarchy that confined him, and he repeatedly tries to transform enemies with personal attachments into instruments of that war. (Chapter 2369)

Demon kings and the breaking of Quinn

The Red Space Quinn enters is governed through Immortui's demon hierarchy. Residents describe five great demon kings, two normally kept at Immortui's side and three ruling regions, while captured Champions embody the failed resistance of the natural inhabitants. Immortui's demons and the plane's native peoples are not interchangeable: the latter existed before his visible conquest, and even the account that credits him with imposing greater order says his new races amplified the world's conflict. Quinn's later uncontrolled “demon form” is likewise Quinn's transformation, not an agent or avatar of Immortui; its connection lies in the vampire lineage and demon blood that can develop it, not in Immortui personally possessing Quinn. (Chapters 2368, 2373, and 2419–2422)

Immortui comes to Quinn after Quinn has exhausted his blood aura, damaged his armour, and temporarily lost access to that demon form. Appearing in his own humanoid body rather than through a host, he first attempts persuasion. He says the Ancient Ones accepted his growth only until he approached their level, then excluded him instead of treating him as an equal; he presents war as the destiny imposed by the universe and offers Quinn a place beside him. This is Immortui's own account and differs in emphasis from Bliss's claim that obsession with a death condition caused the original conflict. The corpus establishes his grievance and Bliss's counter-history, but not an independent ancient witness who resolves their motives. (Chapters 2433–2435)

His promised restoration also proves narrower than the bargains implied to Zero and Quinn. Immortui says he can reconnect energy to someone at the brink of death, but cannot restore a long-dead person's memories and feelings; at most he could make an empty shell retaining some power. His larger proposal is to defeat the Ancient Ones and use their combined control over universal energy and time to reset the universe while celestials and god-slayers retain their memories. Quinn rejects the cost to all present lives. Immortui then activates his colourless power, drains energy and abilities from the surrounding area, tracks Quinn even inside the shadow space by following the energy being consumed, and defeats him once he emerges. (Chapters 2435–2439)

Rather than kill the person he still needs, Immortui forces red energy into Quinn and traps his mind in an ordeal built from the pain, emotions, and accusations of those whose deaths burden him. The process overloads Quinn's system and leaves his body comatose, but Sil, Peter, and Edvard intervene before Immortui can secure him, using teleportation and a clone to move him across worlds. Immortui's punishment is therefore effective as incapacitation but fails as conversion: memories of Arthur and other allies inside the ordeal help Quinn reassert his purpose. The rescuers, the freed Champions, and Quinn then turn knowledge from Immortui's earlier victories into a plan to collect demon-king blood, control Quinn's form, and exploit the limits of the colourless ability. (Chapters 2439–2442 and 2471–2476)

The final breach and contained soul

Immortui pursues the rescuers by linking his awareness to the red energy permeating the Red Space. That connection lets him sense energy within its inhabitants and travel rapidly after concentrating, but each search requires focus and he must test Sil's many clones one by one. During the resulting battle, Sil learns that physical strikes can penetrate Immortui's reactive armour, constant attacks can interrupt the colourless ability, and Immortui cannot use that draining field and red mist power simultaneously. Those discoveries slow Immortui but do not defeat him. He later answers Quinn's second challenge with mist constructs, serpent-augmented blows, and colourless energy, ultimately destroying Quinn's armour, killing him, and extracting his blood crystal. (Chapters 2483–2484, 2509, and 2515–2516)

Quinn's death appears to give Immortui the key he wanted. He uses the blood crystal's retained connection and final emotional imprint to open a route toward the Golden Space, summons Unzoku and the demon fleets, and waits for the breach to grow large enough to accept his own power. Smaller demons and ships cross first, but Immortui himself still faces rejection until the opening matures. Sil recovers Quinn's body, and Mundus uses the surviving Phoenix power in Quinn's armour to create a new body around the restored bloodstone; the demon-king blood gathered by Quinn's allies then allows Quinn to return in a controlled demon form. The revived opponent and Mundus remove the crystal and close the portal before Immortui can cross, turning his apparent victory into a final battle inside the Red Space. (Chapters 2521 and 2524–2529)

Immortui initially matches or overpowers the revived Quinn. He uses the colourless field as his decisive answer until Quinn's blood-shadow coating resists its drain; once active, the field also suppresses Immortui's red mist and enhanced output, allowing Quinn's accumulated vampire abilities, human Qi, shadow, and momentum to overwhelm him. When he abandons the field, Quinn answers with large-scale blood-shadow attacks. Pushed to the edge, Immortui merges the living armour, serpent-like extensions, red crystals, claws, tail, and other demonic traits into a final form. It increases his speed, strength, beams, mist movement, and durability, but it is Immortui's own transformed body—not one of the demon kings, a summoned avatar, or a possessed host. (Chapters 2530–2536 and 2538)

After Quinn crushes that form, Immortui makes a final deterrent explicit: killing him will trigger a “clawback” that removes the power supporting his creations, including vampires, and ordinary celestial death would eventually send him through reincarnation. He argues that a powerless Quinn and his humanised allies would be vulnerable when he returned. Bliss counters that the celestials could prevent a reincarnated Immortui from again accumulating millennia of power, but that is a promise about future policy rather than a tested mechanism. Quinn chooses the immediate end and disintegrates Immortui's body with a blood-shadow drill. The Red Space mist vanishes, demons lose their forms, and nearly all vampires and subclasses revert to humans, confirming the clawback rather than the threatened outcome being a bluff. (Chapters 2538–2541)

Immortui's latest state is more specific than either survival or ordinary death. Quinn's system exempts his own power from the clawback and stores Immortui's soul as a crystal, offering either placement into a compatible being or release into reincarnation. Quinn leaves it contained, reasoning that this prevents the reincarnation Immortui threatened. The corpus never shows the crystal being broken, implanted, escaping, or speaking again through Chapter 2545. Immortui is therefore defeated and absent from the universe's active power structure, but his soul has not been established as annihilated. (Chapters 2540 and 2545)

Appearance and personality

In his direct humanoid appearance, Immortui resembles a grey-skinned man near thirty with sharp, slightly sunken features. His eyes have black sclera, red irises, and white pupils, while long straight hair swept back from his face is divided into black and white halves. A moving black substance covers his limbs like armour, exposes parts of his torso, and bears living red eyes near his hips, leaving Quinn unsure where armour ends and body begins. Under extreme pressure it merges further into him: serpent-like hair, red crystals, claws, wings or extended demonic structures, a spiked tail, and traits resembling many demon races combine into his final form. (Chapters 2433 and 2535–2536)

Immortui is patient enough to build plans across millennia but volatile when control slips away. He recruits with selective truth, appealing to Zero's grief and Quinn's distrust of the celestials, yet openly admits the limits of restoring the dead when he believes a grander universal reset will persuade Quinn. He regards most human and vampire followers as replaceable sources of life and death, threatens families to break resistance, and destroys Jared after using him as a message. His central grievance is hierarchical: he believes the Ancient Ones denied him equality because they feared his growth. Whether or not that account is complete, his actions consistently subordinate individual lives to accumulating power, escaping confinement, and overturning the celestial order. (Chapters 1960, 2310, 2354, 2369, 2434–2435, and 2539)

Powers and abilities

Immortui's capabilities combine celestial energy, a condition tied to death, demon creation, markings, power distributed through the Red Space, an energy-draining colourless ability, and extreme physical transformation. Several explanations come from Immortui or Bliss rather than a neutral mechanical source; where their accounts differ, the demonstrated effect is firmer than either speaker's ancient interpretation. (Chapters 1937, 2434–2436, 2483–2484, and 2535–2540)

Celestial condition, death energy, and reincarnation

Immortui's celestial condition is death: deaths across the region connected to him generate celestial power even when he does not personally cause them. This unusually broad condition lets wars, natural deaths, and the Red Space's engineered violence feed him over immense periods. He can sense and manipulate energy associated with the dead, save someone at the brink of death by returning lost energy, and construct only an incomplete shell from someone already dead. The exact boundary of “the brink of death,” the cost per restoration, and whether he personally performed Zero's claimed experience are not established. (Chapters 1937, 1951, 2435, and 2525)

Immortui can also force a living mind into a death-linked ordeal containing the pain and emotions of people associated with that person's guilt. Against Quinn, the red energy enters through his body, overloads the system, and produces a prolonged internal confrontation that leaves the physical body unconscious. The technique is powerful psychological coercion rather than proven resurrection or literal possession by every dead person shown. Allies and reconstructed memories can affect the victim's response, and removing the body from Immortui prevents him from immediately repeating the process. (Chapters 2439–2442 and 2471–2476)

Like other celestials, Immortui expects to reincarnate if killed without another being taking his condition. His unique clawback makes his defeat withdraw the derivative power sustaining demons, vampires, and their subclasses, although celestial energy remains where separately held. Quinn's system interrupts the expected cycle by storing his soul crystal. At the latest point, the soul can theoretically be released into reincarnation or placed in a compatible host, but neither operation occurs and compatibility is not defined. (Chapters 2539–2541 and 2545)

Demon creation, bloodline, and command

Immortui can turn living creatures into demons and is identified as the source from which vampires ultimately derive. His creations form distinct races with different bodies and abilities, and some can create subordinate races or transform further. He supplies power to demon kings and followers, gives orders across the Red Space, and commands armies through its energy. The corpus does not present a single creation ritual, the cost of making a demon, or proof that every individual demon was personally transformed by his hands; “creation” encompasses a power and lineage whose exact propagation varies by race. (Chapters 1937, 2310, 2354, 2368, and 2434)

This origin creates exploitable interactions rather than absolute control over every descendant. Vampire blood and Quinn's system retain a link that can help open a cross-plane route, demon-king blood can strengthen and stabilise Quinn's demon form, and Immortui's death withdraws most derivative demonic and vampire power. Yet Quinn repeatedly refuses Immortui's commands, and some followers serve willingly while others require markings or direct control. The relationship is therefore a power lineage with a final clawback, not continuous possession of all vampires or proof that transformed characters are Immortui's avatars. (Chapters 2310, 2348, 2357, 2438, 2521, and 2540–2541)

Markings, remote speech, and hosts

Immortui's marking creates a long-range connection to dedicated followers. It can light during mental communication, convey orders, provide celestial energy, conceal itself when inactive, and serve as a channel through which he speaks using another person's body. Magnus can pass a temporary form to others, extending the network beyond Immortui's oldest followers. Marks do not make their bearers equally capable: Jared receives a temporary surge but is still physically limited, while Magnus already has the strength and knowledge to build a major operation. The corpus does not specify the range, marking ritual used by Immortui, or exact division between Magnus's transmitted mark and the permanent original. (Chapters 1960 and 2307–2312)

When Immortui takes active control, the host's eyes glow with celestial energy and their behaviour, strength, and voice cease to be their own. He can use the host to attack, communicate, and kill the body, as demonstrated with Jared. Other marked people act as coordinated distractions without a scene proving Immortui is personally driving each movement. Hosts, marked agents, demon generals, and followers' enhanced forms must therefore remain distinct categories: none is evidence that Immortui himself has acquired a new body or combat form. (Chapters 2308–2317 and 2350)

Red mist and control of the Red Space

Immortui spreads red energy throughout the Red Space until it becomes part of the plane's environment and its inhabitants. It heightens irritation and violence, lets him sense energy absorbed by living beings, carries commands, and feeds a feedback loop in which increased conflict produces more deaths. With concentration, he connects to the distributed mist to search across worlds or condenses it around himself for rapid travel. Searching a universe and accelerating this way both take focus, so Sil's scattered clones delay him and the travel method is unsuitable for a fast exchange in combat. (Chapters 2369 and 2483–2484)

In battle, Immortui shapes the mist into blasts, barriers, portals, giant hands and weapons, remote fists, and serpent-enhanced strikes. He can turn his own body into mist to reposition, spread energy across planetary distances, and produce shockwaves capable of disturbing or destroying enormous areas. The shoulder serpents can react independently, fire condensed beams, wrap his arms to strengthen blows, and appear as patterns on larger constructs. These techniques draw from the same red energy, but their exact energy cost and maximum range are not quantified. (Chapters 2439–2440, 2484, 2509, 2515–2516, and 2530–2536)

The mist is versatile but not unrestricted. Immortui cannot use it at the same time as the colourless ability because that field also drains red energy. Shadow portals let opponents redirect or avoid its constructs, sustained attacks can prevent him from forming a colourless counter, and blood shadow can meet its output without immediately dissolving. Mundus's time control works poorly through dense red mist, but focused use can still affect protected areas; the plane is an advantage rather than an absolute immunity to other celestial powers. (Chapters 2484, 2512, 2515, and 2529–2531)

Colourless ability

Immortui's signature colourless power removes colour while draining energy from attacks, abilities, bodies, and the surrounding environment. He can coat a hand or foot, project temporary balls that create local fields, or expand “Unbroken World” across a broad zone. Blood aura crumbles as its energy is removed, physical strength and breathing decline inside the field, and even Quinn's god-slayer shadow is consumed—although more slowly than ordinary energy. Immortui can also follow the drain to locate energy hidden in shadow space. (Chapters 2435–2439 and 2515)

The ability is not an unconditional nullification. It expands from Immortui and has a range, though no precise maximum is given; projected balls dissipate after a time, whereas the sustained field persists until withdrawn. Shadow body, shadow travel, and later blood-shadow armour slow or resist its effect enough to preserve movement and attacks. Physical bombardment can interrupt activation, and Immortui cannot maintain red mist techniques while the field is active. That final interaction becomes decisive: Quinn endures the drain while Immortui loses access to the mist and enhanced output he normally layers over his physical body, forcing Immortui to cancel his own supposed trump card. (Chapters 2437–2439, 2484, 2515–2516, and 2531–2538)

Immortui can apply the power with finer control as well. Contact allows him to erase energy from a weapon or opponent, he embeds a lingering effect in Sil that Mundus can pause but not remove, and he uses it on himself to remove the sensory impairment caused by Quinn's screech. The corpus demonstrates those results without explaining whether the self-directed orb destroys the impairment, isolates it, or exchanges affected matter; its mechanism should therefore remain unknown. (Chapters 2436, 2484, 2524, and 2535)

Physical power, living armour, and final form

Even without the colourless field, Immortui has speed and strength comparable to or beyond his demon kings. His moving body armour automatically expands to block energy attacks, while direct physical blows and edged weapons can penetrate it. Two serpent-like extensions defend him, attack independently, or reinforce his arms. Champions discover that different tactics make him reveal different parts of this arsenal, which is why no single early encounter supplies a complete account. Constant multi-directional pressure, physical contact, shadow redirection, and attacks timed before colourless activation are the most effective demonstrated counters. (Chapters 2433, 2437–2440, 2484–2485, and 2515)

When Quinn's controlled demon form and blood-shadow techniques finally push him close to defeat, Immortui absorbs and merges the armour, serpents, crystals, claws, tail, and demonic traits into his final form. The transformation increases his physical pressure, allows rapid mist-like repositioning, fires beams from serpent heads and back crystals, enlarges claws through mist, and withstands attacks that had crushed his humanoid form. It has no stated activation cost or time limit, and “final form” is the narrative label rather than an explained evolutionary stage. Its latest and only completed use ends when Quinn overcomes the colourless interaction, incorporates Immortui's shed blood into the finishing attack, and destroys the body completely. (Chapters 2535–2540)

Power progression

Relationships

• Quinn: Immortui sees Quinn as both a derivative of his vampire power and the strongest key to escaping the Red Space. Repeated recruitment attempts become a personal war after Quinn rejects universal reset and threatens to protect his family; Quinn ultimately destroys his body and contains his soul. (Chapters 2310, 2369, 2434–2435, and 2538–2540)
• Mundus: Mundus acts as the Ancient Ones' messenger and repeatedly delays or blocks Immortui's crossings. Immortui respects the nuisance posed by his time power but knows Mundus cannot defeat him alone; Mundus later helps revive Quinn and close the final portal. (Chapters 1965, 1983–1985, and 2524–2529)
• Bliss: Bliss preserves the most detailed hostile account of Immortui's ancient conflict and treats Erin and other god-slayers as safeguards against him. Her account conflicts in emphasis with Immortui's own explanation, so their relationship is mediated by competing histories as well as opposition. (Chapters 1937, 2434, and 2539)
• Richard Eno: Richard's ancient portal gives Immortui access to Earth and enables the seed of vampire power to take root. Later bloodstones and magic-circle knowledge descending from that history continue to create routes between planes, although the exact terms of any direct agreement between Richard and Immortui are not established. (Chapters 1937, 1960, and 2521)
• Zero: Zero becomes a dedicated follower after an unusual encounter and kills in exchange for Immortui's promised help concerning lost loved ones. Immortui uses the marking to direct him toward Erin, while Zero privately recognises that Immortui may not honour the bargain. (Chapter 1960)
• Magnus: Magnus is a permanent marked follower who spreads temporary markings, empowers the campaign on Earth, and builds the Jessica-powered breach. His transformation and choices remain his own borrowed service rather than a manifestation of Immortui's body. (Chapters 2307–2308 and 2346–2356)
• Laxmus: Laxmus worships Immortui as the dead god, takes his name, and interprets the vampire gift as a command to kill. His violence extends Immortui's influence, but the earliest claims about the god's immediate wishes come from Laxmus rather than direct communication shown in the scene. (Chapters 1356, 1763, and 1782)
• Erin: Immortui orders Zero to kill Erin because her dhampir nature can harm demons and potentially Immortui himself. She is therefore a strategic threat to his creation power even though the corpus does not show a direct fight between them. (Chapters 1937 and 1960)
• Sil: Sil disrupts Immortui's first capture of Quinn, disperses clones across the Red Space, and exposes limits in the colourless power and living armour. Immortui's lingering drain nearly kills him, but his rescue and final summons give Quinn the time and insight needed to return. (Chapters 2440–2441, 2483–2484, and 2521–2531)
• Unzoku: Unzoku is a demon king whose appetite and growth make him useful but not wholly obedient. Immortui directs him and later recruits him as the last surviving king for the Golden Space invasion, while Unzoku privately imagines surpassing his creator. (Chapters 2407–2408 and 2517–2521)

Items

No separately catalogued item is assigned to Immortui. The moving armour, serpents, markings, soul crystal, and mist constructs are manifestations or remains of his power rather than configured inventory items in this wiki. (Chapters 2433, 2484, 2535–2536, and 2540)
