Ahriman

Ahriman is the primordial God of Chaos and Darkness known as the Demon of Demons. Bound by seals that prevent him from exercising his full divine power in Hestia, he uses the Crown of Darkness and its bearer, Felix, to extend his influence into the mortal world. His intervention in the struggle with William causes the deaths of William's wives and makes him one of the Half-Elf's most personal enemies. He later joins the invasion of Hestia, only for William to tear his soul from his body and surrender it to Nyx after the invaders' defeat. (Chapters 1062–1079, 1222, 1297, 1436–1462)

Appearance and personality

Ahriman's manifested form is a giant, imposing demon with long black hair, two crimson horns, red wings, and a third eye. He sits upon a vast black throne in his Domain, surrounded by oppressive darkness. Superbia also says that he can appear as a lizard, a snake, or a young man, so no single mortal shape should be treated as his only form. His presence and voice can overwhelm beings across the Domain even while his greater power remains sealed. (Chapters 1062, 1076)

He embodies ignorance, harmfulness, and disorder and openly seeks to cover creation in Darkness. Cruelty is not merely incidental to his strategy: he commands the invaders to make mortals despair and agonize before death, treats Felix and other followers as instruments, and covets divine souls as material for breaking his seals. He is also proud and vindictive. William's earlier victory wounds his dignity, while James's effortless blows provoke disbelief and rage rather than caution. His confidence collapses only when William captures his soul and reveals that Nyx will decide its fate. (Chapters 1062, 1076, 1436, 1451, 1462)

Biography

The Demon Continent and the Heir of Darkness

Ahriman rules an abyss of endless darkness in the north of the Demon Continent, but the seals binding his body keep him from simply imposing his will on Hestia. He therefore selects Felix through the Crimson Crown, making the mortal his Heir of Darkness and giving him divine regalia with which to challenge William. When William and his allies enter Ahriman's Domain, the god turns the contest into more than a duel between two heirs: he manipulates the battlefield with darkness and chains, shields the servants he still finds useful, and reaches for the souls and Divinities of William's wives. The deaths of Ashe, Sidonie, and Chiffon devastate William, yet the God of Death takes their souls after Ahriman violates the Code of Gods by interfering, denying Ahriman the power he hoped to consume. William's survivors finally escape the Domain, but the loss converts Ahriman from a remote divine sponsor into the focus of William's revenge. (Chapters 1062–1079, 1100)

Ahriman later recognizes that killing the women was strategically wasteful: capturing them could have given him Wrath, Lust, and Gluttony, whose Divinities would have accelerated the breaking of his seals. That regret reveals the logic beneath his cruelty—souls and divine authorities are resources for restoring his unrestricted godhood. His plans nevertheless bring him into direct conflict with William and the gods supporting the Half-Elf. Ahriman can deploy enormous Godly power after descending, but the laws restricting gods in Hestia and the seals upon him prevent full use of it. William's side exploits that limit, and Ahriman is defeated by a coalition that includes Gavin, Astrid, Eros, Lyssa, and another divine ally; the later account explicitly states that they could not have won had he been able to use his complete strength. (Chapters 1222, 1296–1297)

The Grand Alliance and the War of Destruction

Ahriman remains committed to Hestia's ruin and coerces Eve into serving as his High Priestess, leaving the young woman with the experience and guarded judgment of a war veteran. When the Army of Destruction attacks, he accompanies it despite not being one of its original members and exercises operational command over the vanguard. He orders Pseudo-Gods to break open the barrier between the Void and Hestia, demands the extermination of everyone in their path, and follows the hundred-thousand-strong force through the breach. The prepared Grand Alliance answers with billions of spells, and the invasion becomes a contested war rather than the effortless slaughter Ahriman expected. (Chapters 1403–1415, 1436, 1468)

William initially conserves his Godslaying power for Surtr, so James takes responsibility for Ahriman. James repeatedly overwhelms him despite having lost his old Divinity, wounds his chest, and reduces the self-proclaimed primordial god to retreating while stronger allies occupy James. When the Army of Destruction withdraws, Ahriman tries to escape through its portal, but William drags him down with a golden lasso, tears the soul from his body, and ends their personal conflict without destroying that soul. In fulfillment of a promise, William gives it to Nyx, the primordial Goddess of Darkness who has opposed Ahriman since ancient times. The last direct evidence leaves Ahriman disembodied, terrified, and in Nyx's custody; what she ultimately does to him is not shown. (Chapters 1448, 1451, 1456, 1462)

Skills, classes, and divinities

Chaos, Darkness, and divine authority

Ahriman's foundation is his authority as the primordial God of Chaos and Darkness. Within his abyssal Domain he controls pervasive darkness, exerts pressure across great distances, and protects chosen subordinates from attacks that would otherwise kill them. His dark chains can restrain or redirect combatants, and the red beam fired from his third eye can pierce powerful attacks and bodies. These effects are demonstrated manifestations of divine power; the corpus does not supply a System class sheet, spell list, or single resource meter for them. (Chapters 1062, 1075–1077)

Souls, Divinities, and the breaking of seals

Ahriman can use divine souls and stolen Divinities to weaken the seals binding his body. He seeks the powers of Wrath, Lust, and Gluttony for this purpose and believes that absorbing the three women's souls would break at least two of his chains. This is a progression mechanism rather than an instantly completed theft: the God of Death's intervention prevents him from retaining the souls, and his later descent still leaves him unable to use his complete Godly power. (Chapters 1076, 1222, 1297)

Shapeshifting and divine resilience

Ahriman can assume animal and humanoid forms, including a lizard, snake, young man, and horned winged demon. His manifested body withstands combat on a divine battlefield and survives a chest wound from James, but it is neither invulnerable nor inseparable from his soul. William can physically extract that soul once Ahriman is caught, after which Nyx can hold and torment it directly. (Chapters 1062, 1451, 1456, 1462)

Power progression

Relationships

• William: Ahriman's interference causes the deaths of William's wives, turning their conflict into a personal vendetta. William later helps defeat him, prevents his retreat, removes his soul, and hands it to Nyx rather than grant him escape or a quick destruction. (Chapters 1075–1079, 1112, 1296–1297, 1462)
• Felix: Felix is the bearer of Ahriman's Crimson Crown and his Heir of Darkness. Ahriman empowers and protects him as a mortal agent, but their bond is instrumental: Felix advances Ahriman's designs and is shielded only while useful. (Chapters 1062–1077, 1222–1244)
• Eve: Ahriman forces Eve to become his High Priestess and draws her into the Central Continent war. The experience survives his defeat as a source of Eve's maturity and wariness. (Chapters 1403–1415, 1468)
• Celine: Celine opposes Ahriman in his Domain and tries to protect William's wives and their souls from his interference. Her patron goddess's later participation in Ahriman's defeat deepens that opposition. (Chapters 1075–1077, 1297)
• James: James assumes responsibility for Ahriman during the final battle and dominates their exchanges, preventing Ahriman from interfering with William's fight against Surtr. (Chapters 1448, 1451, 1456)
• Nyx: The primordial Goddess of Darkness and Ahriman's ancient rival. William fulfills his promise by giving her Ahriman's captured soul, which she takes away for an unstated punishment. (Chapter 1462)

Items

• Crimson Crown / Crown of Darkness: Divine regalia used to identify and empower Ahriman's Heir of Darkness. It chooses Felix and serves as the conduit through which Ahriman advances a mortal champion; it is not established as an item Ahriman personally wears in the present story. (Chapters 1062–1063)
• Armor of Darkness: Protective regalia bestowed upon Felix through his position as the Heir of Darkness. Its defenses belong to the crown's empowerment of Felix rather than Ahriman's unarmored baseline. (Chapters 1063–1075)
• Spear of Lazarus: A divine weapon placed in Felix's service for the confrontation with William. Ahriman is its sponsor rather than its principal on-page wielder. (Chapters 1063–1075)

Mechanics and limitations

• Ahriman is a god, but seals bind his body and Hestia restricts descending deities. He cannot use his full Godly power there, and a divine coalition defeats him by exploiting that constraint. (Chapters 1222, 1296–1297)
• Souls and Divinities can accelerate the breaking of his seals, but he must successfully obtain and absorb them. The God of Death's seizure of William's wives' souls prevents the intended gain. (Chapters 1076, 1222)
• His Domain greatly expands his control over darkness, restraints, communication, and protection. Once William leaves it, the Half-Elf's connection to the System returns, demonstrating that Ahriman's suppression is tied to divine territory or law rather than an unlimited universal effect. (Chapters 1075–1079, 1102)
• Ahriman's shapeshifting changes his presentation, not the status of his soul. Physical defeat and bodily resilience do not stop William from extracting that soul after the final battle. (Chapters 1062, 1462)
• Ahriman joins the Army of Destruction's invasion but is not one of its original members. Its leaders permit him to withdraw with them, yet do not protect him when William settles their separate grudge. (Chapter 1462)
