"Luna!" Celestia called down the hall to her little sister. The dark purple alicorn looked back as she continued to run. Celetsia followed her through the long, twisting halls of the castle.
She soon grew tired and she stopped to catch her breath. It was Celestia's responsibility to keep Luna happy and safe. Not long ago, Luna had been known as Nightmare Moon. She caused havoc in the whole kingdom of Equestria. Now, thanks to a group of six friends, Luna ruled with Celestia once again.
Celestia shivered as she thought about those days.
*There must be something Luna is hiding* she thought *I must find her.*
Celestia began to concentrate.
