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.

Twilight's had some time to think about what happened during the Tirek crisis, and now she has only one question on her mind:

Did Twilight get Celestia's immortality or not?

When she confronts her former mentor about it, she learns some interesting things about definitions, technicalities, and necromancy.

More importantly, she learns that even the greatest of ponies have their weaknesses.

A/N: Mostly TwiLestia friendshipping, and lots of headcanon. Also one or two cameos.
