Tilted Pyramid

From PathfinderWiki

The Tilted Pyramid is actually one of a set of pyramids located in the deserts of Osirion built millennia ago by the mage Aram-Hul. Its companion, the Darklands or Stalactite Pyramid is incredibly located in the earth beneath it, but is inverted, hanging from the ceiling of a large cavern. The Stalactite Pyramid focuses magical energy toward its surface mate, but the exact purpose of this magic has been lost to time.1
