This week's character is:

Garret

An orphan making his living as a street pickpocketer gets caught in the act by a Keeper, a guardian of the world's balance, which recognises his talent and trains him to become part of the Keepers order himself. The boy then leaves the order to pursue a more selfish way, using his newly acquired skills to become the most known and feared master thief in The City. Little does he know, though, that his fate will eventually lead him back on the Keepers' side and even push him to put his very life at stake for the sake of others...

Game: Thief (series)

Trivia: The Thief series is said to have been the first to introduce a full stealth mechanic, based on both vision (hiding behing objects and in shadows) and hearing (enemies can hear your footsteps and other noises you make), which has become common in today's stealth games.
