In Assassin's Creed Mirage, what is Basim's original occupation in Baghdad?

Basim's original occupation in Assassin's Creed Mirage is street thief.

The game begins with Basim surviving through theft in ninth-century Baghdad. His encounters with the Hidden Ones lead him away from ordinary street crime and toward formal training as an Assassin. This origin gives the story a clear progression from opportunistic stealing to disciplined stealth, investigation, and contract work.

Basim later becomes a more prominent figure in Assassin's Creed Valhalla, where he appears as a Hidden One in the Viking-era narrative. Mirage is set earlier in his life and was designed as a more compact, city-focused return to classic stealth gameplay. His starting occupation is therefore different from his later identity as a trained Hidden One.
