Even if the flavor as presented is not totally Forsaken vibe, if the mechanics can work, that's the big thing. So far, my best Forsaken / undead PC race idea was a re-flavoring of warforged, which - as much as I love warforged - doesn't really do it for me.
And really, I'm open to the flavor that OBE is presenting, too - I just really like the idea of an undead PC race, and outside of the Forsaken in the WoW d20 RPG, I haven't seen anything out there. There's nothing stopping me from picturing Tirisfal Glade at the same time I read about the Half-Dead, and from the World Seed philosophy, that kind of mash-up to taste is OBE's goal, too.
I'll take a look for myself later today (found this last night just before bed, and am now at work, alas).
