Regis

Biography

Early role and commitments

Regis manifests when Arthur Leywin awakens in the Relictombs with a shattered mana core and a body he does not understand. Arthur had expected the acclorite embedded by Wren Kain IV to become a conventional weapon, but Regis emerges as a horned black wisp with speech, preferences, and a deliberately irreverent identity. He explains that Arthur, Sylvia, Sylvie Leywin, and Uto all influenced his formation. Although he jokes about being Arthur's weapon, his immediate goals are survival, self-understanding, and establishing that he is a companion capable of making judgments rather than an object awaiting commands. (Chapters 256–260)

That independence develops under pressure as Regis and Arthur learn the rules of their shared existence. Regis can retreat into Arthur's body, store and circulate aether, scout where Arthur cannot safely go, and spend his accumulated power to support their survival, but exhausting that reserve can leave him weak or absent. When Arthur's first Destruction rune begins consuming him, Regis intervenes and takes the burden into himself, emerging as a shadow wolf. The act saves Arthur and gives Regis a stronger body, yet it also binds him to an edict whose hunger threatens his temperament and control. Their constant mockery masks a practical commitment: each repeatedly entrusts his life and judgment to the other. (Chapters 260–272)

During their first ascent, Regis becomes the voice most willing to puncture Arthur's secrecy, pride, and panic. He helps evaluate the djinn remnant, mediates Arthur's violent reaction when Caera Denoir reveals her Vritra blood, and fights as an autonomous partner instead of remaining sheltered inside Arthur. Destruction lets him tear through enemies far above his original strength, but its use can reduce him to a puppy-sized form or force a long recovery, and Arthur's own attempt to wield it nearly burns away friend and foe alike. By the snow-zone conflict, Regis has grown into a huge, horned wolf whose claws and flames carry Destruction, while his decisions show an increasingly stable loyalty that is chosen rather than programmed. (Chapters 282, 307–325)

Returning to Alacryan society gives Regis a different frustration. He shares Arthur's imprisonment, trial, concealment, and work at Central Academy, often remaining within Arthur so that their connection and aether cannot expose Grey's identity. He can still emerge with devastating effect when Arthur is attacked, but watching Arthur gain godrunes and insight faster than he can grow makes Regis fear becoming an inadequate protector. Instead of accepting that widening gap, he tells Arthur that partners should advance together and chooses to train Destruction more deliberately. That admission turns his insecurity into a commitment: Regis wants strength not to satisfy the acclorite's original purpose, but to remain an equal participant in the life they are building. (Chapters 328–340, 349–369)

Later conflict and consequences

Regis's training becomes decisive at the Victoriad. While Arthur challenges Alacrya's champions and exposes his real power, Regis develops a winged, Destruction-saturated form capable of fighting separately in the air. He burns through Cadell's conjured lance, intercepts attacks, and remains above the wounded Arthur protectively, helping turn a public execution ground into their escape from Agrona's control. The victory validates Regis's insistence on keeping pace, but it does not remove the danger of his power: Destruction remains hungry, and success still depends on Regis and Arthur continuously sharing intent, aether, and restraint. (Chapters 370–380)

After returning to Dicathen, Regis expands his idea of protection beyond Arthur alone. He spends aether to support Alice Leywin's healing work, helps stabilize Mica Earthborn while she absorbs dangerous mana, and fights Agrona Vritra's Wraiths after memories inherited through Uto help him recognize them. Separation by portals proves that the range and resilience of his bond with Arthur have grown, but the Wraith battle also shows why that bond matters: Regis can attack independently with Destruction, yet his best results come from coordinating its erasure with Arthur's movement and judgment. His role is no longer merely the weapon that appears from Arthur's body; he is a defender whose choices affect Dicathen's other survivors. (Chapters 390–405)

The remaining djinn ruins and Sylvie's return reshape Regis again. He accompanies Arthur's mixed party through the Relictombs, uses his mutable body and aetheric senses in environments built around unfamiliar laws, and remains present when Arthur's long effort finally restores Sylvie. Her return creates a three-way mental and emotional connection rather than displacing him. Regis supplies blunt humor when Arthur and Sylvie become trapped in guilt or abstraction, but he also takes their fear seriously and lends his focus when Arthur experiments with the last keystone. Their joined perspectives make Regis more than a supporting voice: his different instincts and ability to attract aether become part of how the group approaches Fate. (Chapters 407–447)

Inside the final keystone's possible lives, Arthur learns more clearly how rare Regis's consciousness is. Wren explains that an acclorite can acquire some self-determination, but that a fully self-aware manifestation requires extraordinary will, energy, desperation, and accumulated influences. Arthur consequently tries to awaken the Regis of those constructed lives rather than treating him as a replaceable tool. When the struggle against Agrona reaches Tessia, Regis empties his aether into Arthur, enters Tessia Eralith to assess her collapsing condition, and carries her words across a connection Arthur cannot share directly. He becomes protector, interpreter, and emotional witness at once, even while the effort reduces him to a weakened wisp. (Chapters 448, 482–489)

Regis continues through the negotiations and asuran war as a member of Arthur and Sylvie's family as well as a battlefield partner. Against Agrona Vritra and Kezess Indrath, he spreads Destruction through layered spells, follows their structure with Arthur, enters Arthur to burn corruption away from his damaged core, and then deliberately cuts off the flames before they rupture the surrounding reality. That restraint is the culmination of his long conflict with Destruction: he can unleash annihilation without surrendering judgment to it. After the conflict, he remains characteristically irreverent among the Leywins, teasing Sylvie and Arthur while being included naturally in their home and future rather than set aside as a completed weapon. (Chapters 491–539)

Appearance and personality

Regis first appears as a floating, teardrop-shaped black wisp with small horns, bright eyes, and a flame-like body. Absorbing aether and taking responsibility for Destruction allows him to assume a wolf shape, although severe depletion can shrink him to a puppy or reduce him again to a wisp. At greater strength he becomes a massive shadow wolf with an obsidian, spiked coat, forward-sweeping horns, serrated fangs, and violet fire running over his body. In his most Destruction-saturated state, he can manifest wings of shadow and flame. (Chapters 256, 272, 309, 323, and 379)

His personality combines Arthur's sarcasm and protectiveness with recognizable traces of Uto's aggression and the influence of Sylvia and Sylvie. Regis is vulgar, theatrical, flirtatious, and quick to make a joke at the least dignified moment, but the humor often serves a serious purpose: he interrupts Arthur's spirals, states uncomfortable truths, and refuses to let companionship become obedience. He feels fear, jealousy, exhaustion, and insecurity through their connection, yet repeatedly chooses to risk himself for Arthur, Sylvie, and their allies. By the end of the corpus, his irreverence remains intact alongside markedly greater patience, empathy, and self-control. (Chapters 258, 267, 310, 359, 369, 439–447, and 539)

Power progression

Relationships

• Arthur Leywin: Regis manifests from the acclorite embedded in Arthur and can reside within his body, but their relationship develops as a partnership between linked minds. Regis challenges Arthur's judgment, shares aether and sensation with him, and insists on growing strong enough to protect him by choice. Arthur, in turn, treats Regis's consciousness as singular and worth recovering even inside the final keystone's constructed lives. (Chapters 256–260, 369, 447, and 484)
• Sylvie Leywin: Sylvie is one of the influences that shaped Regis before manifestation. After her return, she and Regis share Arthur's mental bond without becoming interchangeable: Sylvie often supplies restraint and reflection, while Regis provides bluntness and instinct. Together they help carry Arthur's memories and the pressure of Fate, forming a family unit whose connection persists beyond combat utility. (Chapters 258, 439–447, 484, 491, and 539)
• Caera Denoir: Caera becomes Regis's recurring companion during the Relictombs ascents. He teases Arthur about her, argues against reflexive distrust when her disguise falls, and fights beside her through the snow zone. Their banter and cooperation help keep the tense alliance between Caera and Grey from collapsing. (Chapters 273–280 and 297–327)
• Uto: Uto is not Regis's owner or a continuing consciousness inside him, but mana and impressions left through Uto's severed horn contribute strongly to Regis's formation. Those inherited traces include aggression and later memories that help Regis identify Agrona's Wraiths. Regis recognizes the influence without accepting Uto's loyalties or sadism as his identity. (Chapters 258, 398–399)
• Wren Kain IV: Wren created and implanted the acclorite from which Regis eventually manifested. His later explanation establishes why Regis is exceptional even among acclorite weapons: accumulated energy and influences combined with extraordinary will and desperation to produce a fully self-aware being. (Chapters 124–126, 256, and 484)
• Tessia Eralith: During the confrontation with Agrona, Regis enters Tessia to evaluate the damage left by Cecilia's removal and relays Tessia's thoughts to Arthur. His discomfort at serving as intermediary does not stop him from carrying her words faithfully or spending his remaining strength to help keep Arthur and Tessia alive. (Chapter 489)

Mana, aether, and abilities

Regis is not a conventional mana-core mage. His body and consciousness arise from mutable acclorite, while his active power comes primarily from aether shared with or gathered around Arthur. This unusual origin lets him change form, move between embodied and incorporeal states, and wield the Destruction edict, but his reserves, stability, and distance from Arthur impose real constraints.

Acclorite embodiment and shared aether

Regis can dematerialize into Arthur's body, emerge through his chest or shadow, and communicate across their mental connection. He stores aether, feeds it back into Arthur, draws on Arthur's core, and naturally attracts ambient aether strongly enough to assist the first formation of Arthur's aether core. His range of independent movement grows substantially over time, and he can briefly enter other people to sense or stabilize internal conditions. Depleting his reserves weakens his voice and body, shrinks his wolf form, or forces prolonged recovery, so his apparently incorporeal nature does not make him inexhaustible. (Chapters 256–272, 309, 390, 447, 489, and 491)

The acclorite's mutability gives Regis several practical forms rather than one fixed body. The wisp is inconspicuous and suited to sheltering inside Arthur, the puppy form conserves strength after depletion, and the full shadow wolf provides speed, claws, fangs, mass, and reach. He can scout, track, carry pressure into close combat, and coordinate through shared perception even when Arthur cannot watch him directly. His manifested body can still be struck, pinned, dispersed, or exhausted, and damage or separation is transmitted through the bond as pain, vertigo, or emotional shock. (Chapters 256, 267, 272, 309, 323, 390, 425, and 526)

Destruction

Regis houses the Destruction godrune after intervening when its first manifestation begins consuming Arthur. He produces violet-black fire that erases physical matter, mana constructs, aether, and even the structure of spells it reaches. The power can coat his claws and jaws, blaze outward as breath or waves, or saturate his entire body into a larger winged form. Because Regis and Arthur share intent and aether, they can combine Destruction with close combat, God Step, or analysis of an enemy spell's underlying pathways. (Chapters 272, 307, 323–325, 379, 398–399, and 531)

Destruction is also Regis's greatest limitation. Its hunger encourages aggression and expansion without distinguishing ally, enemy, or environment, and early use can leave Regis reduced to a puppy or unconscious inside Arthur. He gradually gains enough control to target attacks, protect allies, and stop feeding the flames before they consume a battlefield or rupture the space containing it. This restraint is learned rather than absolute: powerful uses still demand large aether reserves, expose Regis to the edict's impulses, and require trust in Arthur's judgment. (Chapters 307–310, 323–325, 369, 379, 398–399, and 531)

Combat, sensory, and support applications

Outside Destruction, Regis fights with the physical advantages of his wolf body and the information passing through his bond. He tears through armored enemies with claws and fangs, uses his weight and speed to intercept attacks, recognizes Wraiths through impressions inherited from Uto, and can follow Arthur's tactical intentions without spoken orders. His aetheric nature also lets him interact with Relictombs phenomena that ordinary mana users cannot approach in the same way. He is most effective beside partners who can direct or capitalize on the openings he creates, including Arthur, Sylvie, Caera, and Chul Asclepius. (Chapters 323–325, 340, 379, 398–399, 425, 445–447, and 526–531)

Regis also applies his power in nonlethal support. He gives Arthur emergency aether, helps Alice Leywin treat the most critical casualties, enters Mica to steady the dangerous absorption of Vritra-horn mana, and assesses Tessia from within when her body begins failing. These applications depend on access, concentration, and sufficient reserves; helping another person can leave him diminished when Arthur still needs him. His willingness to spend that strength anyway marks his development from a manifestation concerned with its own stability into a protector of a wider family and community. (Chapters 390, 405, 489, and 491)

Items

• Acclorite: The adaptive material Wren implanted in Arthur is Regis's origin substrate. Its accumulated energy, experiences, and influences eventually manifest as Regis, but after awakening he is a self-aware person with mutable embodiment, not an artifact in Arthur's inventory. (Chapters 124–126, 256, and 484)
• Uto's horn: Arthur and Sylvie absorb mana from Uto's severed horn before Regis manifests. Its energy and residual impressions contribute to Regis's personality and memories, including his recognition of the Wraiths; the consumed horn is an influence on his formation, not an object he owns or a vessel that contains Uto as a living resident. (Chapters 191–194, 256–258, and 398–399)
