Tyumi is a broad-shouldered male orc with slate-gray skin, a broken lower tusk, and a long black braid threaded with copper rings taken from fallen officers. His left cheek bears three shallow scars from a battlefield punishment. He wears a battered soldier's coat beneath dark wizardly robes, both altered to fit his powerful frame. His spellbook is bound in treated hide and secured with an iron clasp stamped with the insignia of a defunct military regiment.

Tyumi is disciplined, observant, and relentlessly ambitious. He speaks in the clipped language of military reports, rarely wastes movement, and evaluates every person he meets by usefulness, loyalty, and threat. He is patient when patience serves him, ruthless when cruelty is efficient, and genuinely fascinated by arcane theory despite pretending that magic is merely another weapon.

Tyumi was born into an orc warband that measured worth in broken shields and conquered ground. He was strong enough to survive the first charge, but not clever enough to satisfy the officers who expected him to become a simple weapon. During a winter campaign, Tyumi found a dead battlefield arcanist clutching a half-burned spellbook. Instead of selling it or using it as kindling, he taught himself to read the diagrams one symbol at a time. His first successful spell was a flash of fire that killed an enemy scout and singed his own eyebrows. The officers saw potential in him, and Tyumi was transferred into the regiment's arcane auxiliaries. Military discipline gave Tyumi what instinct never had, a structure for ambition. He learned that a well-placed spell could break a formation more efficiently than a hundred axes, and that fear was most useful when carefully administered. He rose to a junior command before a failed siege exposed the corruption of his superiors. Tyumi survived by abandoning the regiment with the unit's spellbooks, official records, and enough gold to start again. Now he travels as a soldier-scholar, offering his magic to causes that advance his position. He has no interest in forgiveness or honor for their own sake. He wants a command of his own, a force that obeys without hesitation, and enough arcane power that no one can ever order him into the front line again.
