Bjorn stands six feet tall, broad-shouldered, with straight blond hair and warm green eyes. His smith's apron is patched carefully at the waist, while his traveling coat hangs a little short at the wrists. He keeps his sword polished almost obsessively, and his strong jaw shifts to one side when he chews. His smile is rare, but when it comes, it shows a small gap between his front teeth. A few pieces of cold iron are usually tucked into his belt or pack, unless he is with his Jotunn lover.

Quiet and steady, Bjorn prefers the company of a forge, a workbench, or a clear trail to a crowded room. He respects patience, practical skill, and people who keep their promises. His humor is dry, and his warmth usually shows through small acts of repair rather than kind words.

Bjorn Kholson remembers the cold timberline, the weight of a whittling knife, and the older brother who kept him and their younger cousins alive after their father left. He learned to shape wood before he could properly swing a sword. When he grew old enough to leave, he found work at a forge, first making nails and hinges, then blades. He took to swords with an intensity that unsettled his fellow smiths. A guild master recognized his skill, sponsored his membership, and taught him that a weapon's balance could be as carefully crafted as a fine chisel's edge. He eventually carried his work into the wild, where his forged blades helped him become a practiced hunter of trolls and great worms. Years later, looking for an explanation for his father's absence, Bjorn uncovered the truth: his mother was Jotunn, and sometimes took the form of a moose. He kept that discovery private until a night of drink and family company loosened his tongue. He still carries cold iron out of wary habit, though he sets it aside around his Jotunn lover. Now he travels with his berserker brother, hoping for old treasures, quiet roads, and distance from the complications of his love life. He is fond of his newly met adventuring companion, but distrusts his troll-changeling cousin and worries that his own heritage could pull him toward the same strange fate.
