The mysterious pyramid of Ahn'Selota, also known as the fabled Pact Stone Pyramid,1 is located near the ruins of Tumen in the Scorpion Coast region of northeastern Osirion. The pyramid is somehow linked with the magical pact that united the Four Pharaohs of Ascension more than 6,000 years ago. It is said that Ahn'Selota houses the secret of the pharaohs' powerful pact that joined their fates.23


Paizo published a Pathfinder Module set in Ahn'Selota, titled The Pact Stone Pyramid.
