Those who dwell below

The most powerful race of beings to have ever lived on kertia, they dwell in the upper and lower mantles and have been the cause for many large events such as the creation of the gods, and the displacement of 3 continents causing the giant wind storm swathing the planet currently.

General appearance
dwellers generally are massive beings ranging in sizes that rival mountains. due to living in the mantle and having systems to heat them, they are constantly radiating thermal energy, smaller dwellers are cooler than larger ones, however more agile dwellers are also hotter at a cost of structural stability. Higher tier dwellers have access to higher quality metals and may be hotter without structural stability loss. dwellers have a large flexible "bodies" that are relatively flat and smoothe, with strange rounded fins akin to palm islands in dubai, between each fin is a leg which serves no function underground. on the fins are cilia-like protrusions which are used underground for movement. One sect of the dwellers have developed massive horns which vibrate and create a big fucking beam... of fucking fire, like really fucking hot fire like oh myu fucking god... holy fucking SHiididdd...

not all the dwellers in that sect have horns however but i'll talk about the different heads when they come about. Dwellers are constantly burning around temperatures that make them glow, though when cooled (like hibernating or fucken dead) are a dark greenish, near black and iridescent.

Religion
The dwellers worship their creator, the sun. the sun created the dwellers millions of years ago on a passing comet set for an prehistoric kertia, and once they were able to understand the words of the sun they were instructed to take the four thetan planets for themselves, and to prove their power to the sun. they currently are in a war between themselves, and have been somewhat succesful in taking kertia.
