Thavus stands over seven feet tall, with lithic, gray skin covered in darker charcoal-colored lithic patterns that look like cracks in a mountain face. He possesses the broad, heavy shoulders of his kind, thickened by years of marching under heavy packs and wearing standard-issue infantry harness. He wears his thick, black hair in tight soldier braids and carries a massive greataxe with a blade the size of a man's torso. His expression is usually one of stony indifference.

Thavus is a man of few words and singular focus. He is used to taking orders but finds himself most comfortable when the plan involves charging forward. He values efficiency over flair and honesty over diplomacy. He often treats his adventuring companions as his new squad, checking their equipment and watching their backs with military precision.

Born in the high peaks of the Akannu mountains, Thavus Katho-Olavi was a restless youth who found the tribal rituals of his home too quiet. He traveled to the lowland realms and enlisted in a mercenary infantry company known as the Stonewall Duchy. He served for a decade as a front line breaker, earning the name Stonefist after his axe shattered against a gate and he finished the assault using nothing but his bare hands and the raw power of his Goliath heritage. The discipline of the military taught him how to channel his mountain-born fury into a directed, unstoppable force. After his term of service ended, Thavus found that he could no longer return to the simple life of a mountain herder. The blood of the border wars was still on his hands, and the drumbeat of the march was still in his ears. He now wanders the world, seeking a cause worthy of his strength and a death worthy of a warrior's song. He carries his old sergeant's badge in a pouch at his side, a quiet reminder of the men he led who never made it home from the mud and fire of the lowlands.
