Nightmare Moon has decided to return, to take what is rightfully hers! She wants it her way and the only way to do that is to fulfill the deed no villain has ever accomplished. The death of Princess Celestia herself.

Luna was closest to her, so if she used that against her she could surely prevail. Her long written out plan is going just the way she wants it to. Mystery is in the air, Celestia is trying to find out what is wrong. Feeling like she is crazy! The skies are forever grey, and it is impossible to see whether it's night... Or day.

Who will win this battle? It is not just of strength or worth... But of wits, and courage.
