Then again, I am being a good guy this time through. Next time, I'm going to be the "bad guy," and join the Dark Brotherhood, be a vampire, and do all that. IMO, it'll be a good way to get more play out of the game than to do everything at once.
Also, whoever is talking about that crypt, is it when you follow that Thoronir guy? I've completed that quest, but I guess I didn't search the "crypt" very thoroughly... I may go back to see if I can get back in.
