The Troll Hall Chronicles
Chapel of Celestia
The Chapel of Celestia is a room within the Pyramid of Shadows in which the demonic succubus Danneh was being held captive by the thugs of the dragonborn brigand Remus Pop. It was apparently a temple to the gods of Celestia (Moradin, Bahamut and Kord), and contained statues of two legendary heroes of these gods: one was Goguae, the other was not closely investigated. Goguae appeared to speak to our heroes, but this may have been a demonic trick.
How such a temple came to be in the Pyramid of Shadows is unknown, although it appears that many of the pyramid’s inmates over the aeons have tried to fashion certain of the pyramid’s chambers to their own needs.
