Ah, my two cents is to perhaps start with nothing then. Simply write up the shell of the character and let your writing tell the story.
Can be hard to write up all that backstory for a character though, if you're thinking a Knight you'll probably have to.. Just need to find a day you're inspired and quick write up as much as you can =p.
Pretty busy myself actually. A lot of changes goin on haha. Glad you're doing well, hopefully you'll be around long enough to make a character this time =p
