I don't mind that idea, but I agree with CajunRobinHood that it may be beyond your abilities. But I like the idea of knowing there is a lich somewhere wrecking havoc. 

For my character, I've been thinking a more classic idea: someone that grew up on the streets (that explains her way of fighting) getting some money from underground fighting and odd jobs as bodyguard or basic mercenary here and there. Sometime in the near past, she decided to dip her toes on adventuring, instead of messy jobs, and encountered the party she's travelling now with (I don't mind if it's her first proper adventure group, even first adventure, or only one that finally stuck after some tries)
