Two Gods are cool but four would be amazing the other two would be:
Nenya - Goddess of nature
Ypógeios - God of underground
These Gods are the parents of the creators
Story
As the greatest war the land of Isan had ever seen raged on the overworld, Ypógeios and Nenya, Husband and Wife were inprisioned in a dimension known as the nether, they were trapped there by a Dark Mage for thousands of years.
A Hero loyal to the Gods travelled through many dimensions fighting beasts known only to myths and legend to free the God and Goddess, he freed them but in the process died.
In a final attempt to destroy Nenya and Ypógeios the Dark Mage put a spell on Nenya forcing her to hate Ypógeios, Ypógeios swore revenge on that Mage but he hasn't been seen since, he is said to be living in a land of his creation known as the SkyLands far from Ypógeios.
I tried to make it sound epic but failed ;P
