Official description:
 * This underwater hideout provides your infamous character with safe haven. Those willingly inflicted (or shall we say graced?) with vampirism will find a means to feed, and if necessary, a means to cure their infliction. Hire evil minions, pray to the dark god Sithis, and a host of other functions await.

Features:
 * A multilevel lair for murderous players to find refuge
 * The Font of Renewal, where a player may purge himself of Vampirism
 * The Shrine of Sithis where the infamous player may heal and be cured of disease
 * A Dark Minion, who the player may employ to find gold in a most unseemly manner
 * A 'cattle pen' for vampires to dine
 * An indoor garden of venomous plants, including the notorious Chokeberry to feed to your enemy
 * Various furnishing upgrades, including a study room and storage area
