The Realm of Reality and Nightmare

After spending a considerable amount of time in Collow, Hao Ren was more and more surprised by the ancient secrets that were buried in this weird dimension. At first, he thought that the place was another dimension sandwiched between the material world and the Plane of Dreams. After gaining more insight into the place, he found the remnants of the goddess of creation's power, and beings even more ancient than the First Born or Guardian Giants. He also found clues about the goddess of creation's days before creating life, and now, he had found the precursors to the Guardian Giants and the original version of the Creation Engine!

The "prison" realm hid many secrets, and it all pointed towards an ancient age and truth that no one had thought about before. Yet, outside of Collow, there was nary any mention of this prison in any records!
