Otto is a wiry Lightfoot halfling with weathered olive skin, keen hazel eyes, and unruly chestnut hair that he keeps tucked beneath a patched hood. His clothes are practical, dark, and several sizes too large, altered with hidden pockets and reinforced seams. A narrow scar crosses his left eyebrow, and his small hands are callused from years of climbing, lockpicking, and hard travel. He wears a battered leather jerkin beneath his cloak and carries a rapier, shortbow, and several carefully balanced daggers.

Otto is observant, quick-witted, and outwardly cheerful, using jokes and exaggerated politeness to hide how closely he studies everyone around him. He dislikes bullies and wealthy people who treat hunger as a moral failure. Though suspicious of strangers, he becomes fiercely loyal once someone proves dependable. He prefers clever escapes to direct fights, but he will risk himself without hesitation for a frightened child or a fellow halfling.

Otto Baggins was born in a quiet halfling settlement surrounded by fields, orchards, and old stone fences. His people lived modestly but peacefully, sharing meals, repairing one another's roofs, and raising children who knew every footpath through the countryside. That peace ended when dark forces began moving through the region. Raiders, monstrous servants, and frightened soldiers turned the roads into killing grounds. Otto was blamed for trouble he did not cause after he was caught stealing food from a locked storehouse for starving families. Rather than let the town's leaders risk their own safety by sheltering him, they expelled him into the city.
