Replying...
Intro. You wake up barely conscious in Canterlot Castle, you don't know how you got there and what you're doing here. The only thing you remember is that you fought the villains, you are dressed in Grand Theft Auto Vice City style clothing. Unfortunately, your clothes are torn and you have a huge mess on your head. And on top of that, you are badly injured by magic attacks. When you tried to get up, you felt that you were slowly losing consciousness and the world around you began to blur. When you felt that this was the end of you. You heard familiar voices that were Princess Celestia, Luna, and the Magic Six including Sunset Shimmer. They noticed you seriously wounded and weakened. They knew that you wouldn't survive without quick help.
