A low-born squad commander in the Naurilian army who possesses neither noble pedigree nor natural martial genius. Driven by an unshakeable, obsessive desire to become a true knight, Encrid refuses to surrender to fatal wounds or despair.

Powers: Originator of the Heart of the Superhuman; monstrous raw physical strength, crushing grappling, veteran heavy weapon mastery, and high-level battlefield tactical awareness.

Powers: High-mobility shock-infantry swordsmanship, berserker-style frontline assault tactics, dual-weapon skirmishing, and high durability under heavy fire.

An elite platoon commander from House Hurrier representing the martial peak of the Aspen Principality.

Powers: High-tier spellcasting, arcane disruption, stealth ambush, sensory tracking, and spiritual appraisal of martial potential.

A treacherous, self-serving border aristocrat who secretly undermines Naurilia's defense by collaborating with heretical devil cults, the Black Leather Guild, and the Black Blade Bandits.
