Netherim is a plane where the primal forces of nature reign supreme, and the fiends that dwell within it are as wild and untamed as the environment itself. The landscape of Netherim is one of towering mountains, deep forests, and roaring rivers, with fierce storms constantly raging across the skies. The fiends that call Netherim home are creatures of the wild, with forms that blend the features of beasts and demons in equal measure. They are known to be fiercely territorial and are willing to defend their domains against any intruders, mortal or otherwise.
Nir, the deity of Netherim, is known as the Black Sun for the way his powers shape the natural world. He is a chaotic force of nature, with the power to bring forth tempests and natural disasters, or to grant blessings to those who seek to live in harmony with the land. Those who follow Nir believe that the natural world is the true source of power, and they seek to harness its strength for their own purposes. They view civilization and the trappings of modern society as an affront to the natural order and will go to great lengths to protect the wilds of Netherim from their influence.
