Also, Steven Brust's Jhereg series was based on a long running D&D campaign. Wasn't one of Vlad Taltos's best friends a lich?

It's been a while since I've read them, but I don't recollect any physical description of Sethra Lavode beyond her being more pale than normal. (Nothing near the stereotypical flesh-hanging-off-of-bones-and-glowing-eyes appearance of D&D liches.) While she's referred to as Undead, I think that has more to do with her special relationship with the gods of Dragaera and her longevity than anything else. As with many things in Brust, it's not explained. Nor may it ever be.
