Lorelei was once a member of The Crystal Keepers, who lived in Alidia.
Their task was to raise and lower both the sun and moon in turns. But Lorelei let greed and a desire for power consume her. She goaded the other Crystal Keepers into leaving their home, killed those who stayed, and assumed control over the sun and moon. But she overestimated her own strength, and almost went into Magic Overload. When she had to release the excess magic from her body, she was briefly vulnerable, and The Mantle was able to stop her.
She was put on trial, stripped of her magic, and banished from her homeland. She later died in the wilderness.
But the magic she had once possessed was dark and powerful. It became The Nightmare Forces and, after being unwittingly released by the Wyverns, caused The Fall.
In the future, she was reincarnated as Starlight Glimmer with no recollection of her past. Until Twilight decided to make her an Alicorn.
