Jhoutai is the 2-mooned, ringed planet from which the Sazashi and Verin hail. Only an approximate 16% of the surface is land, with another 20% being Jhoutai Table Coral.
Cradle of Life
Like Eden, Jhoutai is a cradle of life. It is a rich, verdant world, replete with a massive menagerie of life even more varied than Eden both above and below the sea. It's a world that has not seen any extinction-level events, which means that the branches of the trees of evolution where never trimmed and so have only further exploded into increasingly strange expressions of life over time.
The Ring of Destiny
People once believed that the ring, a perfect circle to the naked eye, was evidence that The Wheel has chosen Jhoutai for a higher cause.
One of the most striking features about Jhoutai is the presence of an asteroid belt circling its equator. This influences its tides, temperature, and the ability for ships to take off and reach orbit—part of why the Verin had such difficulty originally visiting space.
Ancient peoples would use the shadow of the ring to determine the time of day, and determined early into their history, by the ring's shadow, the size and shape of the world.
