The Favorite Race Of CARNAGE.

The Lumen plane has been plunged into darkness ever since. Plants need light. They need a lot of light to grow. The darkness impacted them the most and they started to die. But that's the least of the problems that the attention of a demon God brought to the plane. 

The temperature of the plane began to fall in the absence of the light of the sun. Snow fell and the plane was plunged into darkness. A lot of living things died because of these changes. The cold and scarcity of food are the main causes of death. But life will survive. Life will always survive when there is ample Mana.
