Celeste

Celeste is a deceased deity that sacrificed herself to become all of the celestial bodies we see in the sky.

After the birth of the gods eons passed uneventfully as each god focused on his own individuality.

Eventually, the God known as Orthos believed that he had come to understand everything there was to learn.

Orthos came to the conclusion that there was nothing left in the vast emptiness and he began to mold and shape himself into a sphere, falling into himself many times over, condensing down into a perfectly round orb.

As Orthos floated dormant in the void, his sister god, Celeste, became intrigued at what Orthos had done. Inspired, Celeste came up with an equally radical idea.

Celeste rapidly increased her internal temperature, doubling it every second until she exploded herself into a trillion, trillion glowing shards, spreading out indefinitely and filling the entire void with her superheated fragments and creating all of the celestial bodies that can be seen in the night sky, twinkling down on her brother Orthos.
