The Main 6 had gone to Celestia. Things had been going haywire recently. Yona had fallen through the clouds during a tour of Cloudsdale, and Twilight was losing the ability to use her magic.
"Magic is disappearing from Equestria, and nopony knows why.", said Celestia.
"I suspect that Tirek May be the one behind this. However, it is unknown how he could do that when he is locked up in Tartarus.", Twilight responded.
Celestia sent them there to figure out what was going on. Twilight left Cozy Glow to watch the school until they got back. Little did anyone know that Chancellor Neighsay had had enough of the times that the Main Six would go on missions.
