After getting thrown into a cave by the boom of thunder Lyra got up on all fours and stood above what appeared to be a buried chest in the back of a cave. Lyra was bound and determined to get this chest unearthed. First she began to poke at it with her hooves, trying to dig out around the rocks and dirt but to no avail as it was buried too tightly. She looked over to her right and saw an old shovel. She levitated it to herself and began to dig it out. Unfortunately the shovel was horribly rusted and it broke on her. She looked at the shovel and could tell that it was ancient. She said, "Good grief this thing is old! Nopony must have been in here for ages."
She decided that as much as she didn't want to return to Ponyville so quickly, that she would have to go home and get one of her shovels. She was bound and determined to get that chest out of the ground so the following morning she headed back home. Despite rushing into the forest and frantically running around when the storm hit she was able to get back home easily. Once she got back to Ponyville she was stopped by Bon Bon. She said, "Look, I'm sorry for smacking you and belittling you in the restaurant. Do you think maybe we could start fresh?"
Running into Bon Bon brought back all those bad memories from the previous day and Lyra broke down crying. She cried, "No! I can not love a pony who doesn't accept me for who I truly am. I can not be with a pony who treats me like dirt, especially in public." She headed back towards her house and continued, "I'm sorry Bon Bon, but that memory of what you did to me at the cafe yesterday is just too much."
She rushed towards herself and Bon Bon yelled, "Just you wait Lyra, you'll come crawling back to me eventually! Nopony else would ever want you!"
Lyra rolled her eyes and headed into her tool shed, where she grabbed her shovel, which was in vastly better shape than the old one she discovered in the cave. Once she knew Bon Bon was gone she headed back out towards the forest. An hour and a half later she finally reached the cave she had found the chest in. She began to dig it out of the ground. The wood the chest was made out of was incredibly old so Lyra had to be careful not to rip it apart. After an hour of careful digging Lyra lifted the chest out of the ground. She unlocked the chest and opened the first of three books. The series was titled, "The Complete History of Humanity." When she opened the first book and looked at the cover page she was shocked. Underneath the title it read "© 2036." She was ecstatic because all of the old books regarding pre-pony history theorized that the human year of 2036 was the year that humans went extinct.
She dropped the book, began jumping up and down like a school filly and shouted, "SWEET CELESTIA! I AM RIGHT! THEY DID EXIST!"
She knew that she would need to get the chest home so she could read the books comfortably at her kitchen table. Luckily for her there was a full moon that night so she was able to easily find her way home. It was around three in the morning when she got home. She placed the old chest in her bedroom closet until the next day when she would begin to read the history of her favorite topic, written by one of the beings she holds so dear. What she would find would open her eyes to a new side of her beloved humans, a side that was not so pleasant.
