Emmith
The eleventh planet of the Jesenreth Crystal Sphere, a terrestrial world 19,457 miles in circumference. The surface of the planet was once green and fertile, home to an advanced race of humanoid beings who perished in a terrible war against each other thousands of years ago which rendered the air, ground, and little remaining water poisonous, infected with a substance called zuag. Now home only to ruins and strange, mutated creatures and monsters, Emmith is nonetheless braved by many explorers hoping to find the treasure of The Lost Race. Most do not return from beneath the world's copper-colored clouds.
Those that do report that, despite the planet's inhospitability, intelligent beings yet dwell in its vast deserts and mountains, the mutated descendants of the several servitor races kept by the Lost Race. These are the Rodyenko, the Grubar, the Mixlenko, and the Pterrah. Most of these live in nomadic tribes and clans, their existence brutal and full of war. As an adaptation to the harsh, poisonous environment, which is poor in metals, the inhabitants have developed sophisticated systems of martial arts as well as powerful psionic abilities.
There are also widely separated city states, such as Torad-zur. Syndecol Industries is rumored to have a secret base on Emmith, and to be conducting experiments on something they found in the ruins.
