A week after Luna's return to her sister's side, the young princess believes she is ready to be given her once great power back. Celestia offers her a means to regaining it, but at a horrible cost. The price is high: to confront the demons of her past.
A companion piece to my growing series. As well, this is the "Element" continuity reason to Luna's different forms between her first repentance onward.
One-shot.
