Before the rise of the Silver Flame, it was not uncommon to find people who openly worshipped the Dark Six, either hungry for power or making sacrifices to placate the dark gods. Temples to the Six were usually built in hidden places, and when Sharn was created an enormous temple to the Dark Six was constructed beneath the city. In 484 YK, Flamekeeper Jalus Baine led a force of the faithful and exterminated the followers of the Six, and the temple was quickly ransacked. But it was not completely destroyed. Currently, it serves as the headquarters of Daask and the home of the ogre mage Cavallah (LE female ogre mage rogue 3). Cavallah respects the Mockery and the Shadow and has restored their altars, but for the most part the temple was simply a convenient base of operations. She has established a range of defenses in the temple, and brought a variety of unpleasant beasts from Droaam: gricks, displacer beasts, basilisks, and an assortment of other deadly creatures. The wealth gathered by Droaam lies in the vaults of this temple—but seizing it would be a dangerous task.
Many of the Dark Six have other worshippers in Khyber’s Gate, how have established hidden temples; these folk generally practice their faith in private and have little contact with Cavallah.
