Question: Why did you initially turn evil and what caused you to be reformed?

Dear Snowheart,

It puzzles me that you would ask such a question. Do the ponies of today so easily forego learning about Equestrian history. Well, if I must remind you, I turned into Nightmare Moon because I felt neglected by my position in the day and night cycle. I understand now that, even though I may harbor feelings of neglect, I cannot take them out on other ponies. Whatever action I do, it cannot harm another. I was reformed by the almighty power of the elements of harmony and was able to return to my throne as Princess Luna.

Sincerely,
Princess Luna

Dear Snowheart,

Did it ever occur to you that being the bringer of chaos was fun for me?

Sincerely,
You know exactly who this is from.
