Author's Notes:

Your loving mentor,
Princess Celestia

PS. The decree is written but will be signed depending on the results of the visit.
PPS. If you continue to experiment with necromantic anything Twilight, I'm going to force you to undergo Luna's method of education and it involves a great deal of negative reinforcement.
