Dear Princess Celestia,

My name is Lexicon. I am one of the librarians here in Canterlot. Included with this letter are some papers that indicate an incident in Ponyville some years I ago, and I just found them recently. I'm sure you're aware of what had been recorded in them, but I feel they should be brought to your attention. I have not shared this with anypony. Tomorrow, I will hand this to one of the guards to be taken to you. I trust your judgement in regards to these records.

-Lexicon, Canterlot Librarian
