The Keepers Legend (unedited)

All power can be corrupted and each Keeper has a dark side. Anger and despair can change anypony but for the keepers it is ultimately more dangerous, their anger and despair literally transforms them into a evil form. The evil forms of most of the Keepers is unknown mainly because none of them have ever transformed to their evil form, except for Ember and Luna. After the disappearance of the other Keepers, Luna began to change. She became jealous of Celestia because while the mortal ponies played and admired her beautiful sunlight they slept through her beautiful night sky. Luna became so envious and angry that it transformed her into the villain we all know as Nightmare Moon. Celestia told me that she has had dreams, bad dreams, about her evil form. She described it to me as red with a blazing fiery mane. I wonder if any of the other Keepers have had nightmares of their evil form. Luna told me about Princess Ember's evil form, She said that Ember told her about it when she got in a fight with the stallion she loved. Ember's evil for turned her coat pitch black, her hair and wings lit into flames and her eyes were as red as the flames of hell. Unfortunately that was the day Ember began telling herself that her powers couldn't be controlled and that she was destined to be the princess of destruction and death because she truly believed that those were the only things fire were good for.
