First Great Cataclysm

The First Great Cataclysm was a galactic catastrophe that took place in 4,400,000,000 BBY.

When a supernova threatened the galaxy, the powerful Celestials refused to use their powers to prevent it, despite the pleads by the demigod Mendax.

The supernova was allowed to take place and as a result many Celestials were killed. Due to the amount of casualties sustained by the Celestials, Mendax and many others seceded from the Celestials and formed the Dark Celestials in protest of the their former leadership.
