Splugo is a wiry male goblin with moss-green skin, oversized amber eyes, and a sharp, foxlike grin. His black hair is carefully slicked backward with grease, making his deliberate grooming stand out against his patched and poorly fitted clothes. He wears a child-sized brown leather coat with the sleeves cut short, a red scarf wrapped three times around his neck, and one polished brass button that he constantly checks to make sure it is still there. His boots are mismatched, but his thieves' tools are kept immaculate in a velvet-lined pouch.

Splugo is observant, opportunistic, and theatrically confident. He speaks as if every conversation is a negotiation he has already won, but he is more protective of the frightened and desperate than he admits. He enjoys clever plans, locked mechanisms, rooftop routes, and anyone who appreciates a well-maintained tool.

Splugo grew up beneath the dripping bridges and crowded market lanes of a sprawling city, where goblin children were expected to be hungry, quick, and forgettable. He learned early that people noticed a loud goblin, a dirty goblin, or an angry goblin, but rarely noticed the quiet one carrying away their purse. An elderly street thief named Vessa took him in after catching him trying to steal a brass button from her coat. Rather than punish him, she taught him the value of patience, clean tools, and always knowing three ways out of a room. When Vessa disappeared after crossing a powerful criminal guild, Splugo inherited her velvet-lined thieves' kit and a hand-drawn map marked with routes that no longer appear on any official city plan. He left the streets to discover what happened to her, taking work as a scout, burglar, and occasional messenger. Splugo does not consider himself heroic. He simply believes that anyone who owns too much deserves to lose a little, and that every locked door is an insult waiting to be answered.
