Forum:Writing A Book...

Just wondering a few things. I've started to write a book, just messing around. I realize it's all made up but is it acceptable to have say, a jedi who survived the purge, go live with Obi-Wan on Tatooine? This is right after the purge so it has no effect on the films..And wondering if theres things I SHOULDN'T do while writing this, star wras wise.

Thanks.
