Sacrifice Door

Sacrifice Doors, also called Obsidian Doors or Stone Doors, are seemingly ancient artifacts that pre-date the cannibals or Sahara inhabiting the peninsula. It is assumed that the doors were created by the ancient ones, who also created the obelisks. Each Door has an offering pedestal in front of it, where the player can lay items, including but not limited to: sticks, skulls, rocks, and bones. Once three items have been placed, the player can fit through the door opening, upon which the doors will swing open fully. These doors can only be found in the deeper parts of the caves. In some places, the doors have fallen, due to possible violent activity, or perhaps natural cave shifting.
