Kaelen has a face like a dried creek bed, deeply etched with lines of worry and battle. His skin is the color of aged parchment, stretched tight over a jagged jawline. A silver-white scar carves a path from his left temple down to his chin, pulling his lip into a permanent, sardonic half-sneer. Despite his weathered look, he keeps his salt-and-pepper hair cut militarily short. He moves with a heavy, rhythmic tread, though he has a surprising grace when reaching for his ledger or his blade. Contradictory to his grim aura, he wears a ring of pure, delicate gold filigree on his pinky finger, which he rotates constantly when deep in thought.

He is a man of rigid professional ethics who harbors a profound distaste for the individuals he employs. He treats mercenaries with a cold, transactional courtesy but will spend hours ensuring a fallen guardsman's family receives their pension. He is weary of the world's monsters but views them as mere broken gears in a machine that needs oiling. He acts with bored indifference in safety but becomes terrifyingly focused and sharp when a threat is identified.

Kaelen was once a sergeant in the city watch of a now-fallen metropolis. He lost his status, his family, and his faith in the crown during a plague-induced riot that burned his district to the ground. He joined the Sallow-Warden Guild as a common guard and worked his way up through sheer survival. He once personally executed a mutated Great Beast that had decimated three trade caravans, earning his scars and his promotion. Currently, he is struggling with the guild's dwindling profit margins and the persistent interference of Elara, whose mystic approach to the beast problem he finds dangerously inefficient.
