How do the undead count as a race/nation? I recall them being created by a necromancer in the other games. But now it sounds like it's just a natural part of death.
Further, why do they cling to the notion of gender? It seems rather meaningless once the flesh has rotted away. Given how they like to act superior to the living I expected Yorick was going to say they're above such issues when gay marriage was brought up and how the Elves and Dwarves are both fools for obsessing over such a trivial matter.
