Princess Celestia, ruler of Equestria, did something dumb all because of boredom. She managed to open a portal to another dimension when a rock band name System Of A Down performed in a concert. To make things worse, her sister, Luna, scared her and caused the performers to get sucked into Equestria. From there, Celestia would get to know about them and their music.
