Xanatua
From The Thalassan Sphere
Summary
Xanatua is a relatively small exoplane discovered by Goa and Pranna and bound to Tierra. Most of the gods (descendants of Li Stardancer) live there. It's described as an idyllic land of eternal sunshine surrounded by turquoise waters.
During the Cataclysm, the tethers holding Xanatua to Tierra snapped off, sending Xanatua flying off across the ethereal plane. Its residents can't return to Tierra until it is found and retethered. This is why most of the gods are thought to have abandoned Tierra in her hour of greatest need.
