Sacred Haven of Debauchery

My mood changes constantly, almost every five minutes.

Same here! But not exactly every 5 minutes, but it can change suddenly and for no reason, but that's okay because my nickname is just my name, which doesn't depend on my mood.
Also, at the beginning, when you're accompanying the Emperor, right? In Oblivion, there are bears

(though not Grillz), and they were supposed to eat you.

Yes, the Emperor left, he abandoned me :( I'm all alone now! And I was eaten by rats.
And why specifically bears?
