Farr is a Rodian (yes, he should probably be speaking in Rodian. But you never know, maybe someone does a great job and we'll have an english-speaking Rodian.) technician, or, more specifically, a slicer/outlaw tech, both hacking into places he probably shouldn't and scavenging supplies to create or augment his ship and equipment. He is a *very* shady character who is involved with criminal enterprises and hopes to create his own network of ciminals to enrich and rule his own small area of space. He, in the end, wants to be a crime boss. He has been recruited by Jabba the Hutt to track down this Butcher, who's been causing trouble for Jabba lately, and who has quite a talent at vanishing. His slicer codename is Soak. 

He is one of the main characters.

Soak is cunning, ambitious and resourceful, though he is, by no means, an action man. He is usually the mastermind behind the plans. His morality is, clearly, very much evil, but he will join up with the other characters to stop the even worse Butcher. 

Reference Characters: Michael Corleone, from The Godfather trilogy.
