Dear Princess Celestia,
It is me your faithful student, Twilight Sparkle. This is my last letter to you for I have passed on. Looking back at the first day you told me to meet friends, I thought it would be a waste of time making friends but seeing all of the great memories I have had with my friends, I don't regret any of it. Now I see Pinkie Pie all by herself, I cannot help but shed a tear for her and wish to come back to her to comfort her in her time of need. But if there was anything I learned from my years being in Ponyville would be Friendship is the most powerful force in Equestria and sometimes you need to sacrifice yourself for the people you love. So when it was my last moment there in Equestria, I knew it was all worthwhile just to see the smiles on my friends faces. So this is my last lesson of friendship I could share with you and it is my time to go onto the great beyond. Farewell Princess Celestia, I wish you the best.
-Your Faithful Student,
Twilight Sparkle
