Faren is a joinable NPC, playable in Baldur's Gate 2: Shadows of Amn and Throne of Bhaal. Found in the Trademeet Jail, Faren is a True Neutral dual-classed Fighter/Thief.
When asked about his past, Faren gives you a mock-suspicious glare and blithely says that there is little to tell. Hailing from Trademeet, he worked for the town militia when he was younger. After leaving this job - an event he recalls somewhat ruefully - he travelled to Luskan with a group of adventurers, with whom he made close friends.
He is glad to be back on the road, saying he gets itchy feet if he stays still for too long, and despite his laid-back approach to life he seems happiest when wading into action.
Faren is able to romance male or female PCs of any alignment and any race. There is detailed non-romantic content for PCs who are not interested in Faren as a romantic interest.
Overall, if you want a laidback romantic interest, a character who is friendly without being clingy, and a thief who can take care of himself in a fight, then Faren will be good for you!
