The Upperworld is a small "pocket" dimension adjacent to Earth; an inter-dimensional nexus between Upperworld and Earth exists at Tulan-Ziuva, "the Place of the Seven Caves," somewhere near the ancient city of Chichen Itza on the Yucatan Peninsula. Very little is known about Upperworld other than it appears to be built upon a small planetary object enclosed on all four sides by the bodies of four giant iguanas.
