The fate of Canterlot High

"I'm glad you came here as quickly as you could. The alternate world has found additional ways to get to and from Equestria. The cause is one of the inhabitants was able to open a portal to Equestria, because of an amount of remnants from your Element of Harmony. It was enough to make a portal to and from Equestria, so we need you, Twilight Sparkle, to close the portal, and stop destruction of Equestria." Celestia explained,

"I don't understand! I thought portals could only open once every thirty moons!" Twilight exclaimed,

"Not in this case. This certain inhabitant made it nearly impossible to close the portal. Only you, Princess Twilight, can stop the evil inhabitant and save Equestria, once and for all." Princess Celestia explained,

"Princess, I don't think I can do it. I've been there before, and even though I liked it, I had to be like a filly. I had to learn everything again, and I don't want to start over again." Twilight replied

"Sometimes, you have to do something that you would not like to do. Do you understand the difficulties of your task?" Celestia asked,

"I do, Princess Celestia." Twilight reponded. Princess Celestia walked to a tacky window. "That, Twilight Sparkle, will be entering the alternate world."

Twilight stepped into the portal.
