Antimatter is comprised of oppositely charged molecules that destroy itself and what ever it touches. It is a pre-cosmic substance that embodies true entropy, erasing objects from reality. It directly opposes Dark Energy which destroys Antimatter on contact.
Description
Due to its impossible nature, living organisms cannot properly perceive the nothingness of Antimatter directly. When Antimatter is looked upon, it takes the appearance of smoky white fog with a radiant purple glow. Antimatter infused with Dark Matter, its primordial opposite, takes on a slimy mucus-like consistency and it loses its corrosive nature. Antimatter brought into a Universe will instantly destroy itself and anything it is touching.
History
Nowhere
First in Existence
For all eternity, before, during and after all of existence, Antimatter dominates the extant realm of Nowhere. Nowhere existed before all of creation, and is comprised of nothing but Antimatter.
The First Beings
Over trillions of years, the physics defying Antimatter formed three primordial, Cosmic Entities. These entities are comprised of or products of Antimatter in the Empty Void. The first of these beings was the Entity, embodiment of primordial madness and destruction. Later, the great Void before creation, Khaos came into existence. And lastly Yahweh, the true embodiment of light and creation was formed.
A Tool For Creation
Primordial Monsters
Yahweh used Antimatter as well as his immense power to create numerous monstrous beings, the Primordial Monsters. These beings were comprised of magically infused Antimatter, allowing them to hold their shapes and gain sentience.
Ancient Deities
The Primordial Void, Khaos, was a being comprised of Dark Energy, which absorbs and assimilates Antimatter. Khaos slowly absorbed Antimatter from Nowhere causing her to grow larger and more powerful. She used this new Dark Energy the Primordial Protogenoi, and later the Ogdoad.
