Four beings fly through the space between dimensions. Their destination is Earth. To the four of them, this reality is little more than a toy. A place where the rules of their home do not apply. A place where the fabric of reality is subject to their will. They are gods and our world is their play-thing.
Each of these four invaders have taken an interest towards the local population, specifically humans. Human's lead complex lives. Pull one string and the whole thing changes. Pull a lot of strings and the whole becomes something entirely different.
The four like humans and the societies they have build, but they think that humans can be so much more and they each want to use their powers to help the humans, to help them evolve. They will achieve this by changing a human's body in bizarre and imaginative ways. Each of these "gods" has a chosen theme and will change the humans in accordance with their doctrine.
Jennop; God of Animals and Myth. Jennop has found beauty in all of Earth's creatures and wants to merge that beauty with the humans. Jennop also enjoys human literature and the various beasts there in. Jennop wants to bring these myths into their reality.
Yaun; God of Creativity and Perversion. Yaun is the most creative of the bunch. To Yaun, each human is a blank canvas, begging to be made into something more, something greater, something unique, something unexpected, and something exciting. Yaun can be cruel. Yaun can be generous. You never know what you're going to get with Yaun.
Twion; The Merging God. Twion has been moved by human relationships. The idea of how humans will dedicate themselves to one another even if it tears them apart has captured Twion. Twion wants to bring these relationships to whole new level. Twion is usually not as perverse as Yaun, but Twion can be just as cruel, if not more cruel than his ethereal comrade.
Slavail; The Swapping God. Slavail is much more subtle than its counterparts. Most people will not even notice if they had been touched by Slavail. Slavail likes to swap the various aspects of human beings. Sometimes these changes can be barely noticed. Other times, these changes can be just as odd as the other gods.
*Author's Note: feel free to add your own God into the mix just make sure to include an in-depth introduction chapter and leave as open-ended as you can.
