General Onimaru, Wartime Strategist
General Onimaru is Quince's top military man. You can think of him like Sun Tzu in that he's a master of the art of war. He is known for his strategic planning, tactical maneuvers, use of terrain to his advantage, his ability to discipline an army, and his ability to know the enemy.
Onimaru is actually an outsider to Flagstone, though he's won many battles in foreign lands and at least one on Flagstone soil against the former regime. Grave was just a boy then, and he lost his father that day. Onimaru claimed the Stormborne family sword as a war-prize, and were it not for the intervention of Mistress Persephone, Grave would never have received his family heirloom.
Many years later, Quince was able to recruit the General. There, Onimaru raised an army and due to his harsh style, the troops called him the Flagstone Enforcer. He also investigated unorthodox forms of military force, including the use of wild elephants and an experimental program to create clockwork soldiers with the help of the then-head of Flagstone Research & Development: Max Geiger.
General Onimaru is a formidable foe to anyone who would threaten Flagstone or its right to rule. That goes double for outlaw barristers and mutant stone golems who would sow the seeds of dissent with their illegal Fantasy Strike tournament.
