Tenebris is a Daikura from the dimension of Shoshek, and first came into the universe 23 billion years ago. It was the ultimate Daikura of Shoshek. It was able to defeat all Daikura in Shoshek, and, after consuming all matter in Shoshek, broke through dimensional barriers. It began the Celstian War. Following the explosion of the life core, a few remnants of Tenebris remained, some of which landed on Ourea, and some on Earth. On Earth, these remnants decided whether humans were kind or evil. However, on Ourea, a planet without any animals, it simply festered. When humans arrived on Ourea, their essences tampering with the gems awakened the remnants of Tenebris, which poisoned the hearts of humans and began the War of Conquest. Inevitably, it was sealed away by 9 individuals. However It always seeks to return.
