I had this dream that I had this quest to find unique Vampiric abilities. I raided this rather decrypt looking library and found 4 wings, each wing had a little pedestal with blood in it (Think of a certain companion quest). Drinking from the blood granted a new ability.

In the center of the complex was a pedestal with a glowing magic flask, which I knew would allow me to store one blood point for future consumption (Think of it as a way of getting rid of high vamp rating if your sneak is low). Upon picking up the flask, I heard some distant doors thunder open. A horde of daedra started to invade the library searching for me..

Then I wake up, and thought that'd make a halfway decent ending to a quest for gaining unique powers
