Seles

A gleaming white sphere, it appeared in the skies above Heroda long before its dire twin Pandom. Broad plains of silvery grass sweep across chalky white soil stopping only where jagged mountains reach almost out of the atmosphere. All of this is perched on sheer shelfs of land that floats above seas of molten platinum. Reality on Seles was extraordinarily weak before it was moved into the reality shadow of Heroda.
The people of this world are the Pontic, a tall and slim humanoid with Bluish skin and four arms. They are split into two major factions who call themselves either "Penitents" or "Mechagus". The distinction stems from a split millennia ago. After the Penitents opened the way to Mount Celestia, they began to martial their people to ascend the mountain and find solace there while leaving their world behind.
The people living here were and still are technologically advanced, there was a faction of them that felt the world was salvageable and that foreign gods, no matter how well meaning, would not be their path to salvation. These "Mechagus" began a grand project to create an engine that could move their planet to safety. In doing so, they accidently created a connection to the plane of Mechanus, issuing forth an orderly force of Modrons who swiftly understood the idea behind the grand engine and began to effect changes and repairs that would enable it to actually work. The Mechagus resisted at first but the changes were mind blowing to them and they slowly but surely began to work with the Modrons.
Upon the engines completion and activation, the world was moved into the nearest stable Reality Shadow which happened to be Heroda.
Though they realized that their worlds execution was stayed, the Penitents still maintain that their goal should be to ascend the celestial mountain and this pilgrimage is the eventual goal of nearly every member of these people. The length and depth of the pilgrimage is not seen as important, some only going as far as the first layer while others disappear for centuries to attain the highest levels, often never returning.
Due to the more malleable reality here, gods of neutrality, law and good carve out their own realms here.

The Pit of Gears
An impossibly large engine of arcane technological design takes up a large portion of the dark side of this moon, shielded with shimmering glyphs and enormous brass plates from the molten platinum that roils beneath the landmasses it delves deep into the crust and is managed by legions of Modrons. They are slowly but surely expanding the engine, an act that is contested on multiple fronts by the other inhabitants of the moon. 

Mount Celestia
The mountain where the first penitents would pray for salvation, opening the way through their combined faith to Mount Celestia on the inner planes. Though the beings there answered the call, they were unable to change the fate of the world. Instead what was formed was a path to salvation by climbing the mountain, where they would be able to find their way to the Seven Heavens of Mount Celestia.
