Sonic's Origin, The birth of a hero.

Princess Celestia stood in her tower worried, she could feel the dark forces starting to move but to what purpose? She had been without sleep for many nights and her sister Princess Luna quickly became aware of this. Luna then started to keep a closer eye on her sister, she didn't know what good she could do to help her but she wanted to be there just in case.

"Sister really I'm fine" said Celestia.

Luna had finally had enough, and asked her sister to join her in the gardens to speak about this matter.

"Sister you haven't been sleeping for 6 days now, you of all ponies should know that I'd notice this, I control the night and enter other ponies dreams" Luna said. "Please sister just tell me what's troubling you" Celestia stood there, unable to find the words to properly explain her troubles to her sister. "I've been feeling the forces of the darkness move in ways that concern me" explained Celestia, "but on top of that, there are times when I myself cannot see what is truly taking place."

Princess Celestia sat down in the garden, she stared at the ground trying to make sense of all of this. Luna sat down beside her.

"Sister, how come I myself cannot feel the same forces moving as you do?" asked Luna. Celestia looked at her sister in confusion, "You mean to tell me that you haven't felt anything at all?" Celestia asked Luna.

Luna thought to herself, "Maybe it is because I was once Nightmare Moon, and the powers of the darkness are more in tune with me, I am the Princess of the night after all" explained Luna. Celestia nodded in agreement, it was plausible, in fact  Luna had been Nightmare Moon for many years when she was banished, so the darkness had plenty of time to bond with her. Luna stood up, "Let me try to focus on this and see if I can feel what your describing" Celestia jumped up "NO DON-" but it was too late. In a blinding flash the darkness that Luna once held as Nightmare Moon started to pour out of her. Her body started morphing again into the shape of the wicked mare. Celestia focused her magic, she had to be quick if she was to save her sister.

She summoned the powers of the suns light and tackled her sister to the ground. The pain that Celestia felt was excruciating, the powers of the darkness burned her body in several places, but she cared little for her pain, her sister needed her and there was no stopping her to save her beloved sister.

Celestia called out to her, "Luna! hear my voice and come back to the light!" Luna winced in pain and agony, trying desperately to suppress her dark power, "Sister!" screamed Luna, she focused all of her energy to stop the transformation, Celestia casted her magic on her to help alleviate the pain. Luna found her light again and started suppressing the flow of dark energy. In a few short second, Luna was back to her original self, gasping for breath she turned to her sister horrified by her injuries.

"Sister , I'm so sorry, I didn't me-" Celestia cut her sister off "It's ok Luna... you're ok."

Luna started casting her healing spells on Celestia, but Celestia stopped her, "Send word to Princess Twilight, Princess Cadence, and Prince Shining Armor, after all that just happened we need to prepare for the coming storm."
