Berethal

Hailing from the now Putrid Plane, Berethal are the remnants of a once great and mighty species. Their history is tightly tied to that of the once Dark Living Plane, and their downfall followed shortly after the undeath of this massive being that is the Living Plane.

The divinity Uil was a being of enormous power that increased it by fusing with the colossus that was the Dark Living Plane. He created the Berethal to be the immune system of it, and they were far more powerful than any other being in the whole dodecahedron, since the Plane made them stronger and they made it healthy in return. For many centuries they protected the enormous beast from demonic invasions and decay, but theirs was a hopeless fight.

But long story short: after millennia of the absence of The Creator, the Plane began to accumulate endless little mistakes, and the scion of different demons grew to eat and debilitate it. The Plane couldn´t die, because it's very essence was Life. And so it began a torturous path towards undeath, and those so tightly bound to it suffered the same fate, seeing their forms forever twisted, and their souls decayed. After many years of boundless wandering, they came to the surface, close enough to the Desert Plane as to be heard by the Palen´Aran, which asked their creator to help them out, and with the power of two great gods, Uil and Yvel´Zin´Paen, the Berethal were able to cross to the Desert Plane, and they were able to change their element from Life to Plasma, easing the pain enough as to let them fight for their newfound home.

They now are completely stable, but they don´t forget about their golden age, and even though they know the Putrid Plane is beyond saving, they trust they´ll be able to be what they once were by any mean possible.
