Black Pyramid

The Black Pyramid is the heart of Xibalba, situated upon the apex of Xibalba's central hill. Within the Black Pyramid, the sahkil tormentors reign over their minions, bicker among themselves, and devise increasingly more nightmarish plans. Beneath the Black Pyramid is an incomprehensibly vast cavern of agony, and it is said that a portal to the Netherworld is hidden deep within the Black Pyramid.
