Obsidian Duke

The Obsidian Duke is a Nemesis whose dense, mutable obsidian body makes him a durable front-line combatant and restraint specialist.

Biography

Nemesis campaigns and uneasy neutrality

The Obsidian Duke enters battle against Randidly with the other Nemeses, attacking with an obsidian battleaxe and accepting their mission of inflicting damage to gather Aether for their home worlds. He later suffers heavily in operations against Earth’s defenders, binds captured opponents in obsidian, and shields allies during confrontations. By the Special Investigator’s trial, he favors Nemesai neutrality and choosing a victor afterward, showing calculation alongside his earlier direct aggression. (Chapters 588, 592, 909, 911, 1243, 1377)

Appearance and personality

His body is composed or sheathed in dark obsidian that can flow in liquid form around his limbs. The material chips under powerful blows, yet he can recover and reform it. His rumbling speech, crossed-arm posture, and blunt objections give him a grave, pragmatic presence. (Chapters 909, 1243, 1377)

Abilities and progression

The Duke shapes obsidian into a battleaxe, defensive mass, and thick restraints capable of wrapping another body. His image is described as heavy and persistent, supporting a style based on endurance, pressure, and interception. Sustained damage can leave him laboring to reconstruct his body, and the Jade Prince’s radiant image injures him badly enough to require recovery. No named class or exact advancement stage is established. (Chapters 588, 909–911, 1243, 1277, 1297)

Relationships

  • The other Nemesai are his operational peers, though he does not always agree with the Bandit King’s political instincts. (Chapters 592, 1377)
  • The Jade Prince is a major counterweight whose pure, radiant image contests the Duke’s heavy persistence and leaves him injured. (Chapters 1277, 1297)
  • Neveah strikes through his obsidian defense when he interposes himself between her and the Bandit King. (Chapter 1243)
