In the ancient past, Faust was the strongest of all alicorns who gave birth to Celestia and Luna. All Faust wanted was to live in peace with her two daughters after their father passed away during the war against darkness that is just known by the name Void. Unfortunately, the void monsters were just slowed down and not banished from their realm.

High Alicorn Council "pleaded" for Faust to help them to banish these void monsters so they could live in peace. Faust had no chance other than to help them. Faust managed to banish these void creatures back to the abyss that spawned them, but with a price. All these years Celestia and Luna thought their mother had died like their father fighting to protect the world, but fate has seen to it that their mother gets to see her foals again.
