Temple Obscura is a colossal mix of mosque and cathedral, of Eastern minarets and Western fluting. All of it fashioned in green-veined black marble — within is the very foundation of their rites of passage, their madness, their very corruption. Those pass through the Temple effectively "dance the Black Spiral." A ritual that takes place within the labyrinth leading them to the heart of the Wyrm itself. Some return somewhat lucid; many almost functional. None return sane.
