Located in the upper right hand corner (of most sanctums), the Morgue is a section of the Darkside that contains miscellaneous information. You'll find items such as the back-story to the game, histories on the different Bloodlines, and the histories of Relics.
Other exciting things are also there to keep you busy while you're waiting for your timers to refill. For fun, why not check out the Vampire Theatre and stream a movie, or read a player-submitted vampire story?
It's all fun, all for you!
