GOBOOM is a lean, soot-black Kenku with ragged charcoal feathers, bright brass-colored eyes, and a narrow beak marked by a small silver ring. Their wings and shoulders are wrapped in dark leather straps carrying lockpicks, wire, chalk, and small stolen tools. They wear fitted black leather armor beneath a weather-stained burgundy cloak, with a rapier at one hip and a shortbow folded beneath the other wing.

GOBOOM is alert, irreverent, and theatrically confident. They enjoy unsettling pompous people by perfectly imitating their voices, and they treat every conversation as a chance to collect useful information. Beneath the bravado, they are deeply protective of vulnerable people and become unexpectedly gentle around children, prisoners, and anyone who has been silenced.

GOBOOM learned early that a Kenku voice can be more valuable than a purse of coins. They were raised in the back rooms of a thieves guild, where their talent for mimicry let them imitate guards, merchants, crying children, and even the guildmaster's secret knock. Their first real job was meant to be a simple burglary, but GOBOOM discovered that the guild was using captured Kenku as disposable messengers and blamed the theft on an innocent family. They broke the prisoners out, stole the guild's ledger, and vanished into the night with half the city searching for them. Since then, GOBOOM has survived as a burglar, lookout, courier, and occasional blackmailer. Their criminal contact still feeds them rumors and jobs, while the stolen ledger remains hidden somewhere only GOBOOM can find. They became a Thief not for wealth alone, but because every lock, wall, and guarded secret represents something that powerful people believe they own. GOBOOM intends to find the guildmaster who betrayed the prisoners, expose the names in the ledger, and make certain that no one can ever claim a Kenku is only useful as a tool.
