Fantastic it was 2am when I got the keys, so tonight I get to examine my new quarters and then go loot the heck out of Skyrim. Boring old quest line but not a terrible perk at the end of the day. Nice to have protected quarters with no need to lay out cash for a house!
I guess the big question is which side quest now, as I am bored with the main quest right now?
1. Dark brotherhood
2. Companions
3. Thieves guild
DB is, so far, a really interesting story line. You must croak some folks who seem harmless to you so beware of that. Companions is pretty good with a surprising perk or un-perk depending on your POV.
Spoiler You must become a werewolf to complete Companions.
I have a very bad attitude toward thieves so I declined that line. Odd that I am playing DB but won't play thieves but that's role play for ya.
