Fahm, also spelled Fam, leads the mercenary group known as Shadow or Shadow Brokers. This character masterfully employs disguises, frequently presenting an outwardly innocent or feminine appearance that leads to mistaken female identification. Beneath this deceptive facade, Fahm engages in clandestine operations with morally ambiguous undertones.

A core strategy involves working undercover as a waitress. This role serves as an effective cover for covert intelligence gathering, enabling access to restricted environments and private conversations critical to the group's assignments.

Fahm wields shadow magic, allowing concealment within darkness to become visually undetectable. However, this concealment only masks visual presence; adversaries can still hear Fahm during operations.

Initially operating independently with the mercenary band, Fahm eventually crosses paths with Ars Louvent. Following their interactions and likely recognizing mutual benefit or aligned goals, Fahm transitions from leading Shadow to serving directly under Ars Louvent as one of his retainers.
