I'm wondering if Falmer count as elves for the sake of Wuuthrad's double damage dealt to elves. Of course lore-wise they are technically elves but does anyone know if they actually count as elves?

They count as elves for another particular quest. It'd be a gross oversight for it to be left out in this instance.

Orcs should count, too.

Hm and I guess they would at that, easy to forget to think of Orcs as Elves.
