That's not bad either but i would think you'd have to be a vampire first to take over Movarth Lair.

As far as the quest goes to become thane, it's possible that's its related to it but i'll see about testing some stuff if i can not do it and still become thane. I'm on PS3 so it's probably unlikely without using console commands.
