What happens if say, for example, you're a werewolf and serve Nocturnal? Would you go with Hircine to join the hunt`? Or serve Nocturnal? Do the two Daedra fight it out for your soul?

Another question: do different races go to different realms of an afterlife? If so, what if two different races get married? Will they be split up in death for all eternity?

Another question: Lore wise, (Skyrim Spoiler!) is Sovangarde bigger than what we see in game? Sitting in a giant hall drinking mead and eating fine food would be great for a couple of weeks, but for eternity?

Last question: What happened to the souls that Alduin fed on? Would their consciousness simply cease to exist forever, denying them of an afterlife and eternal life?
