-How far does Shaitan carapace go? We know it covers everything but the face/front upper body in the end, but can it grow further or in uncommon ways? (Say, uh, maybe like a monster or something. I don't know good examples--)
-Can Shaitan carapace be different colors than black? Not saying rainbow carapace, but maybe having white, or a dark tint of other hues other than greyscale? The wiki just says they're black but I wanna make sure.
-What are Mercalan faith's view on pre-marital sex and prostitution?
-Can elves become vampires without a real issue? I mean, the ears aren't in the racial menu...
