Here is a character bio for my Rogue, Phineralthus Flickwort. I don't know much about the geography of FR, having spent most of my time in homebrews, but feel free to play off it. Character Sheet coming soon...
The son of self-proclaimed Sembian nobles, 'Phin' (he really dislikes Phineralthus) was forcibly removed from the family manor at age 18, when his father caught him pinching gold from the family vault and distributing it to un-wed mothers (Some locals speculated it was palimony).
The father, terrified that his boy might one day besmirch the family name, immediately dismissed him from the household. And much to the father's surprise, Phin turned and walked out of the house without so much as a flinch, muttering something about "a phony and barmy, old codger."
Phin later fell in with a group of rogues in town who were more well known for their drinking and wenching than burglary and guile. After a while however, Phin took over leadership of the gang (known as the Farnsworth Fangs), in hopes of embarressing his father (whom, as a half-witted, false noble, was none to popular anyhow).
After a few successful raids (mostly on his fathers household) Phin's face and heritage became too well known by the local authorityes and he gladly skipped town, hoping escape his father's bumbling, narcissistic reputation. The Fangs are part of his past, but Phin holds a soft spot for them as he credits them for escaping his father's (whom he hasn't had contact with in some time) house. As far as Phin knows his tail is clear (though he's hardly checked) but he sometimes gets a bit jumpy when the authorities are around, being that he nicked enough gold to earn the ire of a few angry merchants. Phin's clipped accent and insufferable avarice, make him instantly recognizable to anyone from his hometown, where his story has become somewhat of an urban legend.
Then he figured things out and was really really angry, particularly when he saw the demon wearing his sword and the warlock wearing his white robes of the archmagi (damn use magic device).
