What if the dark sides of Luna and Stygian lived lives separate from their other half? What if Luna and Stygian had a relationship before their madness and banishment? and if they had Older siblings? This is a story about what could happen. this is a collab with myself and Redwallover28!

Also this is part of my What Could have been world same as Blazing shimmer

We (Redwall and myself) hope you enjoy this tail!

Celestia was sad and confused. Her beloved sister Luna turned into a Alicorn of nightmares, calling herself 'Nightmare Moon' and she had had to use the elements of harmony to stop her from plunging the world into a forever night.

She was unsure of what to do next when she noticed a secret chamber and inside the chamber was a shrine. Inside the shrine was many picture and love notes.

Celestia found a diary of her sister saying that she had fallen in love with the Pony of the Shadows, or Stygian as he had been known before giving into the darkness.

NOW Celestia understood the reason behind Luna's madness. After all, when Starswirl and the other ponies of disappeared so had Shadow. But since no pony (including herself) had known of Luna's relationship. But knowing that she were gone she let the room. She hid the room with a very strong illusion spell, nopony would enter this room, ever, if she had a say in the matter.

Celestia would have preferred to burn everything, but it was not hers, she could only hope Luna no longer held feeling for the demon.

Celestia Held the sun in place as her newly returned sister Raised the moon if front of the sun, creating the first eclipse in 1,0100 years!

Everypony put on there glasses so not to damage there eyes, but if they didn't have them on, they would have seen the dark beam of light shoot from the moon, and into the everfree forest.
