Voidling of Equestria: Fallen Memories

Thousands of years ago Shiera An was cursed with white hair and magic since birth. Though her childhood was rough, she desired to protect her kingdom, and thus became a soldier. It was there in the militia that she eventually found the man that would be her one true love. They were both highly skilled in combat, and stood among the elite of the elite in all the land. She eventually became a general, always loyal. But when the Emperor died, her husband suggested that she take over as Empress. She had no desire to rule or to obtain such a title, but her lover was confident she was just what the kingdom needed.

A month later, mutiny occurred. Her best and closest friend betrayed her, along with her own husband. They took a portion of her army and fled. Not a few months later, Shiera was finally slain in battle. As her husband held her dying body in his arms, seemingly regretful of his betrayal, she died with tears in her eyes.

But heaven did not await her.... Instead she fell into the Void, and was trapped there with other souls and unspeakable horrors that dwelled within, but eventually, she escaped and managed to slip safely back into existence....but the world she returned to was not her own. This world had no humans, and her own body had changed. Changed into that of a pony....
