From getting their powers, to past heroes... to meeting heroes from another city, this is where all of their adventures are stored. The Principal Trouble only covers what Celestia knows... Chaotic Harmony covers what the heroes POVs of everything is.

Celestia is the fun loving principal of Canterlot High... where everything is normal. At least it was until this school year started up. Suddenly she has to deal with two new students, one with issues, one with anxiety, figuring out how to convince her students to be school proud and not clique proud, oh...and figuring out a new drill to do whenever a villain attacks too close to the school. Did I mention she also has to deal with the random appearances of the seven new superheroes? Yeah... this school year is definitely one for the history books.

After a run in with the Dazzlings where they reveal exactly how much they knew about her past, Sunset did exactly what anypony back where she came from would do. She sang a song about her feelings, letting it all out. What happened at the end of her song though is what is bothering her. She knew her friends at the time transformed anytime they played music... she didn't realize that she could transform too. The problem? She transformed into a humanized phoenix not a humanized unicorn.
In an attempt to learn why she would transform into that, she runs away back to Equestria to do a little investigation into the matter. With her friends from both sides of the portal trying to find out what's bothering her, and give her a helping hoof, I mean hand, can she find out the truth behind Sunset Shimmer...?

AU. In a world that has forgotten Ponyville, a Kingdom known for their friendships, Discord must prove it's existence and his innocence in a self appointed quest to save his one true love, his precious Lady Fluttershy.
Can he battle the forces of darkness, and light, to save the day to bring Harmony back to the land and free his love?
