Finx
"Hey, who's the lich here? You? I didn't think so."If you've ever heard of "restless dead," Finx pretty much fits the definition to a tee. After becoming a lich, he somehow lost his phylactery to other, apparently more devious members of the world, and now works for them out of fear for his very existence.
Of course, this won't stop him from endlessly hunting Aldran for revenge, and as a result often puts his "duty" aside for another chance at revenge. Until his superiors find out, that is.
