Yggdrxilknigaknignxi (Yggy) and Mygnoga'mishgopoog. (Mygnog), the World Parents

Yggy: The World Mother. She is the goddess of Plants and Rebirth with a particular fondness for Fungi. She is generally represented as an enormous fungus surrounded by smaller children.
Mygnog: The World Father: He is the god of Ooze and Death. He is usually represented as an amorphous blob.
It is said that the Prime Material Plane was created when Yggdrxilknigaknignxi latched onto and began feeding off of Mygnoga'mishgopoog. Together they birthed the plane and life on it. Now, however, they want to bring the world back to themselves. Thankfully, though, few will follow them, as the World Parents tend to want to absorb beings that are not like them....
