Iskahn, Tenth Champion of the Dark Territory’s Ten Lords Assembly and leader of the Pugilists Guild, was born into a tribe that revered physical mastery. From age five, he endured brutal training, forging his body into a weapon-resistant fortress through Incarnation—a mental discipline amplifying physical resilience. Unshakably confident in his capabilities, he scorned those dependent on armor or lacking strength, derisively dubbing the immortal Integrity Knight Sheyta Synthesis Twelve "Grandma."

Commanding Pugilists at the Great Eastern Gate, Iskahn rebelled upon witnessing Emperor Vecta’s disregard for his soldiers’ lives. He gouged out his right eye to weaken the Seal of the Right Eye’s control, then brokered a truce with Asuna and Alice. Redirecting his forces to stall invading American players, he aided their strike against Vecta.

His rivalry with Sheyta morphed into mutual respect and romance through clashing blades, their banter over hypothetical children masking deepening camaraderie. Post-war, as the Dark Territory’s Supreme Commander, he mediated peace treaties between the five races and the Human Empire. Settling in Obsidia with Sheyta, he embraced fatherhood upon their daughter Leazetta’s birth—alternately called Lisetta—exhibiting a paternal warmth mirroring an ally’s demeanor.

Governed by accountability for his subordinates’ lives, Iskahn prioritized diplomacy over militarism, opposing Vecta’s apathy. Though once contemptuous of non-combatants, alliances with Sheyta and human allies reshaped his perspective, transforming him from a solitary warrior into a strategist dedicated to lasting peace.
