Grimma is a towering Goliath with slate-gray skin marked by natural patterns resembling granite veins. He stands seven and a half feet tall with a massive, muscular frame honed by years of military service. His head is bald, and his piercing blue eyes possess a keen, tactical focus that belies his savage occupation. He wears rugged leather harnesses, wolf-fur pauldrons, and carries a notched Greataxe that has seen countless battles.

Stoic and disciplined, Grimma approaches every conflict like a siege. He speaks only when necessary and values competence above all else. Unlike many of his kin, he possesses a sharp, analytical mind that he uses to evaluate terrain and enemy formations before the first strike is even thrown. He is deeply protective of those he considers part of his 'unit'.

Born in the high peaks of the Cloud-Splitter range, Grimma was recruited into the Iron Vanguard, a renowned mercenary legion, at a young age. His natural strength and surprising tactical aptitude led him to the rank of sergeant. He led many successful raids, but his career ended during the Siege of Oakhaven. His commander ordered a suicide charge that sacrificed his entire squad for a minor tactical gain. Grimma was the only survivor. Disgusted by the cold calculations of high-ranking officers, he broke his standard and deserted. He now wanders the lowlands as a mercenary with a conscience, carrying the weight of his fallen soldiers in every strike he makes. He seeks to find a cause worthy of his rage and his loyalty, refusing to ever again be a pawn in someone else's game.
