"Yes", said Twilight Sparkle digging in her room. What she was looking for was something that she did not know it was till until later. "Come quick ", said Princess Luna, her voice sounded worried. Twilight came running down the hall soon forgetting the worried sound in her voice, Princess Luna was wet eye looking at Princess Celestia. Celestia looking at Twilight, said one thing, her last thing," portal," in a weak voice. Then Princess Luna turned around and walked up the large stairs and Twilight came after her.
In Luna's head something was itching inside, something came to her mind.
Then Twilight looked in a awe as Princess Luna opened a door with a portal of some sort. Then Luna walked over and did some magic as the portal lit up. Then she said in a strong voice," Twilight the only was to save princess Celestia is to go in this portal for a magical green plant called Yaminer." Twilight thought she must whatever she can to help Princess Celestia. Then she went to her room and packed what she was looking for, Hope. Then she went into the portal and left.
The thought came to Luna Princess Celestia is forever dead and Twilight Sparkle is now gone.
My Ponies,
I remember the time when I was free, ruler of my land and keeper of peace. Now I was salved by Luna, my sister who I always loved. It was not the nightmare that was inside her long before, it was her true form Moonlight Swept. I had not known she could be what she had become, but it had happened. I am going away forever very slow and in pain. I wish for the ponies I love to be safe. My dear ponies be safe for that is all you have. Love is the key and flee
Your Princess,
Celestia 
The Princess died and Twilight was never to be seen. The letter got out, but to whom is uncertain.
My Ponies,
I am now my true form, MOONLIGHT SWEPT and I am here to give you ponies some proper teaching. Hope that
some ponies can fly at night.
Your NEW Princess,
Moonlight Swept
Twilight read the note and felt anger.
