Zetle is a wiry, rust-red kobold with soot-dark scales along his snout, bright yellow eyes, and one chipped horn. He is small even by kobold standards, but carries himself with theatrical menace. His leather armor is patched together from stolen scraps and painted with crude black claw marks. A long cloak, oversized hood, and carefully arranged bundles of cloth conceal Sadro, the kobold perched on his shoulders, and Arbo, the kobold hidden beneath him. When Zetle needs a free hand for mischief, one of his companions emerges from the disguise while Zetle pretends to be a strangely animated pile of clothing.

Zetle is a spiteful little hellion with a talent for theatrical insults, suspicious bargains, and escaping through spaces no sensible creature would attempt. He loudly claims to despise society, yet watches crowded streets with fascination and secretly envies people who belong somewhere. Sadro standing on his shoulders and Arbo hidden below him keep his worst impulses in check, though Zetle occasionally extends an arm from their disguise to steal something, wave at a magistrate, or slap a passing noble.

Zetle arrived in the great city with grand plans, a stolen sack of turnips, and the firm belief that civilization rewarded clever creatures. The city disagreed. He was cheated by merchants, chased from respectable lodging, and eventually recruited by a gang that valued his small size more than his well-being. He learned to sleep beneath market stalls, lift purses without being noticed, and vanish through drainage tunnels before angry victims could identify him. His first real companions were Sadro and Arbo, two fellow kobolds who helped him survive after a disastrous burglary left all three of them wanted by the same cruel guildmaster. The trio developed their famous disguise out of desperation. Zetle wears the outer cloak, Sadro rides on his shoulders and supplies the tall silhouette, while Arbo crouches beneath the layered fabric and moves their shared feet when Zetle needs to reach somewhere impossible. Together they became a single, shambling figure known in the poorer districts as the Three-Legged Rat. Zetle insists he is the leader, although Sadro's steady judgment and Arbo's practical caution regularly prevent him from making catastrophically stupid decisions. He now works as a rogue, thief, courier, and occasional nuisance, seeking coin, revenge against the city's comfortable elite, and any opportunity to remind society that it created the problem it fears.
