Laen Sima is a towering goliath standing nearly eight feet tall, with slate-gray skin marked by pale stone-like birthmarks across his shoulders and jaw. His black hair is braided with scraps of red military cord, and his amber eyes are constantly scanning for danger. He wears well-maintained chain mail beneath a weather-stained cloak, carrying a greatsword across his back and a flail at his hip. His hands are scarred from years of drills, climbing, and close combat.

Laen is direct, protective, and unexpectedly gentle with frightened people and wounded animals. He respects competence more than rank, enjoys simple contests of strength, and believes a promise matters most when keeping it is difficult. He is uncomfortable with abstract plans that ignore the people affected by them.

Laen Sima was born among a wandering goliath warband that measured adulthood by endurance, discipline, and the willingness to stand between danger and the vulnerable. He remembers little of his earliest years except the rhythm of marching feet and the stern voice of his first drillmaster. When raiders attacked a mountain settlement under the warband's protection, Laen was among the youngest fighters to survive the defense. He learned that strength alone could not save people. Someone had to hold the line when everyone else was afraid, and someone had to decide when orders had become an excuse for cruelty. Laen eventually joined a lowland army, where his size made him a living siege engine and his blunt honesty made him a difficult subordinate. He became known for breaking enemy formations with his greatsword, disarming officers with his flail, and dragging wounded soldiers out of collapsing battle lines. He deserted after his commander ordered an undefended village burned as a warning. Laen now travels as an adventurer, seeking causes worth serving rather than banners worth saluting. He still follows the habits of a soldier, but his loyalty belongs to ordinary people, not to kings, generals, or anyone who mistakes obedience for virtue.
