The Ouroboros Pyramid is the central building of Ouroboros.
This is the religious center of the Ouroboros. The ground floor holds ritual baths for males and females, the conjugal meeting room, and private bedrooms. There is a multi-purpose common area where meals are served and at night it is used for sleeping quarters by the Daughters. A storage area contains foodstuffs, potions, poultices, and clothing. A well stocked kitchen is here. The second floor holds the barracks for Hecate's elite guard. The third and final floor is Hecate's private bedroom. One thing not shown on the map is an escape tunnel that Hecate had installed in her bedroom. By pulling a lever on the back wall, the floor under the lever pivots and dumps whoever is standing there in a chute that leads to secret door at the rear of the pyramid on the first floor. A tunnel beyond the door leads under the city wall and out into the desert.
