STORY:

There was a snap, followed by the cracking of ancient gold.

Celestia, bearer of the sun, was losing.

She couldn't scream even as her strong wings turned to nothing but rags attached to her burning back, as her own sister's corrupted blinded rage shot every deadly spell she knew as a mare called Nightmare moon, Celestia would not give her the satisfaction of hearing her scream.

A light sparkled; magenta filled with hope as the last of her sane mind vanished. She blinked to refocus, reopening to the eyes of another. A mare she thought was as dead as her mortal soul, Daybreaker.
