[2nd Person Perspective]

Working as a waiter at Canterlot's various social gatherings is a nice job. Especially since you began chatting with the cello player of the usual quartet, Octavia. You've gotten to know a lot about her, but one night there seems to be something on her mind. You offer her a drink to ease her nerves and you bring your glasses together in cheers.

Next thing you know, you wake up in a strange hotel room in a town you've never been to next to a certain gray mare.

There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.

A crime has taken place in Ponyville, and Octavia is the main suspect. Vinyl needs to find a defense attorney before her sister's trial begins. However, not a single lawyer agrees to help them. When everything seemed lost, one mare agrees to take on Octavia's case... the best defense attorney in Equestria: Lyra Heartstrings.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?
