Lich seems to be a forest spirit of a Black Rollam Bird in Held's Forest, if the vague allusion in Trinity is to be believed. Similar to what Michaela was.

In House of the Undead, however, he is in a human form as the waiter. So he must have incarnated in some way at some point. I'm sure we'll get some kind of explanation in that chapter, so speculating any further than the current information doesn't seem prudent to me.
