Uhh, I planned it as the first art in the sequence of kind of giantess goddess monstergirl story. But something went wrong…
Anyway, the story:

At the start, there was nothing. In the void the snake called Ouroboros was dozing off. Her dreams were turned into pieces of a world that was created around her. But this world did not live for very long. She realized that there wasn’t enough supervision so she creates 4 daughters, and sent them to control the world since she was too lazy to do that herself. Balance was created, and life began.

Mongea - the world created from the dreams of the Ouroboros - is divided by climate into 4 zones, corresponding to the sisters. Unfortunately, sisters did not learn to live peacefully…
