Raxus

A race of somber, slim giant humanoids who called themselves the Raxus are the original inhabitants of the world of Pandom, long before it found its home in orbit around the world of Heroda. They stand between 9 and 12 feet tall with 4 angular eyes on their forehead and cheeks and a fifth vestigle, light sensitive eye on the back of their necks. Their dark grey skin is mottled with large freckles and spotting. They have 4 blunt digits as hands and their feet are typically unclad, ending in thick flat feet reminiscent of an elephant or rhinoceros. They dress in simple leather and cloth, their armor and weapons run the gamut between high technomagical guns and the like that have been salvaged or maintained for centuries and frightfully low tech scrabbled together survival gear. The Raxus remain a highly magical species even in their fall from grace, though clerics are exceedingly rare among them as the concept of gods are alien even now. There are a rising amount of Warlocks among them however as more and more they grasp at ways to turn their species fate from its seeming path. 
An advanced species, they once covered the entirety of the world with their cities. They used magic to bend reality to their whim, creating marvels and openly ripping at the seams of their world while ships plied the air and technomagical creations crawled across the surface. 
A millennia of slow dissolution and weakening of their worlds reality however slowly forced incredible changes on the world. Anomalies and abominations wreaking havoc on the landscape and transforming most of the world into alien, dangerous lands. Where once was a verdant, temperate world there was now a strange desert riven through with the cracks of impossibly deep canyons filled with deep grey forest or vibrant and toxic fungus. The world overall chilled as well, leaving the once vibrant Raxus civilization with a narrow band of civilization in the still warm equator. This change was so slow, so incremental that for thousands of years it was barely registered as a phenomenon, much less a widespread one. 
The equatorial lowlands were fortified against the now dangerous world and the society of the Raxus became more and more suppressive. As the worlds reality slowly decayed, the desperate inhabitants split into multiple factions who fought against each other as well as working to try to find a solution to their worlds destruction. Two of the largest factions came to similar though still devastating idea and banded together to create a monolithic portal, they sacrificed millions of their kind to force open connections to the inner planes as a method of escape. Little did they know where they were making this portal. 
cacophony
More portals would open on their own, Demons and Devils and other fiends stepping through with their hordes and carving out their own realms. The Raxus barely exist as a coherent people now, many of them forced into service to various fiends and Herodan gods that have claimed Pandom for themselves. There are scattered fortresses and cities in the deep wilds of the world, the only free city of Raxus exist in a state of precarious war with the environment and their fiendish neighbors.

Pandom

The large red moon that orbits the world is the remnants of a separate world that has been able to anchor its reality to Heroda. Pandoms attachment to the Great Wheel came before it found itself orbiting Heroda. A dark red, blasted world it is covered in desert with incredibly deep canyons crossing its surface like cracks in an egg. Thick grey forests are found in many of these canyons and there are also deep running rivers that flow here. There is a band of dark ocean covering almost all of the equator, Islands peppering the surface like grains of spice.
