What does it mean to be immortal? Celestia has lived for too long. Her memories are old. She has seen many ponies, and many places, and many times, and many stars, and many dreams. She wakes one night to find she does not know the ponies and the stars of today from the ponies and the stars of any other day she has lived. She no longer knows what was real and what was only dreamed.

She desperately searches for the one pony she knows could not have been a dream.
