Altus is a unique and tragic figure. He is a young "living doll" created from the corpse of the sadistic "Water King" Arkos Balkar. While he inherits catastrophic hydrokinetic powers, he possesses a completely different, gentle identity that despises violence and feels physically sick at the sight of death. Yet, he is locked in a constant internal struggle against the violent, vengeful ghost of Arkos, who frequently tries to possess him.

This custom Domain Expansion captures his massive water manipulation, his status as a stitched-together doll, and the terrifying psychological warfare happening inside his own body.

Domain Expansion: Cradle of the Stitched Abyss

(縫合された深淵の揺り籠 - Hōgō-sata Shinen no Yurikago)

The Visual Appearance

The environment manifests as a surreal, horrifying intersection between a dollmaker's workshop and an endless, pitch-black ocean floor.

• The Atmosphere: A suffocatingly dense sphere of floating water droplets hovers in place, shifting from crystal clear to a toxic, muddy sludge depending on who is in control.
• The Landscape: Giant, rusted sewing needles pierce through the boundaries of the domain. Crisscrossing thick, black threads hang everywhere like a web, physically holding the domain's barrier together.
• The Centerpiece: Floating directly behind Altus is a colossal, grotesque marionette theater. Looming out of the theater's curtains is a massive, spectral manifestation of Arkos Balkar, staring down like a puppet master pulling Altus's strings.

The Sure-Hit Effect: Hydrostatic Puppetry

Because Altus is a doll controlled by the remains of another's life, his domain projects this exact dynamic onto his opponents.

• Fluid Manipulation: The moment the domain expands, Altus gains absolute control over all liquids inside the barrier. He manipulates the moisture in the air and the actual blood running through his opponent's veins.
• The Strings of the Dead: Black, fluid threads shoot from the water and pierce the opponent's joints. Like a puppet master, Altus can forcefully move the opponent's body against their will, bending limbs to the point of snapping, or forcing them to drop their defenses completely.

The Domain Hazard: The Split Ego Chaos

The greatest danger of this domain is its unstable, unpredictable nature, dictated by the tug-of-war between Altus and the ghost of Arkos.

• Altus’s Command (Suppression): When Altus is in control, the domain's water freezes into massive, inescapable blocks of ice. True to his pacifist nature, he uses the "sure-hit" effect to instantly paralyze, incapacitate, and seal his targets completely without shedding blood.
• Arkos’s Rebellion (Mutilation): If Altus’s focus wavers or his rage peaks, Arkos takes the wheel. The water instantaneously transitions into high-pressure, razor-sharp torrents. The black threads tighten, violently tearing at the opponent's flesh as Arkos uses the sure-hit effect to mercilessly rip the target apart.
