The Warp

Overview
The warp is a sect of reality that exists alongside our own, running in parelle to it. Often attributed to the forces of chaos that burrow their way into our reality, it's laws are unlike anything else in existence or nonexistence. A constant whirlpool of ideas and emotions, infinite universes and galaxies, all colliding and impacting to form a current of pure chaotic energy. The main cause of this energy is the nature of The Warp and its accounts of creation. Most living creatures capable of any sentient thought, such as humans, animals, and monsters, attribute to fueling The Warp. They do so by simply having emotion and ideas. For every belief and idea that comes to said sentient creature's mind, The Warp creates a universe in which this idea is absolute. For example, a narcissistic person may believe they are the most perfect person in the world. The Warp takes this idea and belief and creates a universe in which it is true. However, another person may believe that this narcissist is a horrible person. Again, The Warp creates a universe where this is true. Naturally, these universes collide in ideas and realities, resulting in a release of chaotic energies. Of course, this happens a literal infinite amount of times, for every single idea and belief in every single sentient creature that is capable of contributing to The Warp.

Landscape
The Warp, as stated above, is a collaboration of all ideas and beliefs, crammed into a limited space. As a result, The Warp is never the same as it was only moments before. In fact, in most cases, it is simply impossible to exist in The Warp, as the energies simply do not allow for matter or energy as we know it to survive the barrage of forces. The only known example of an area where physical beings can exist in these energies is The Eye of Terror, which is the hole between our reality and The Warp.

History
It is currently unknown how The Warp came to existence, and most likely never will be. It is as old as all reality, seemingly born when the first thought was had, whether by a god of some sort, or something else.
