Chaos Theory.
Not many ponies understand it. Heck, not many creatures are capable of understanding it. But, it is a branch of magic--and every branch is studyable. Juniper Cure knows this, and is determined to discover all she can.

Welcome to Regrets in Retrospect, a story about the new age of Equestria.
About 400 years or so after the show, Twilight Sparkle now runs a large city-state where Ponyville and Old Canterlot once were. Dubbed Harmonia, the Princess of Friendship's domain has become a melting-pot of cultures and ideas, allowing for many magical and technological advancements. Harmonia is also home to one of the most prestigious schools in the nation (some argue the world), Six Elements University.
In addition to running both Harmonia and SEU, Twilight has also taken on six personal students affectionately called "the Harmony Division". Their mentorship emulates the virtues of the Elements of Harmony, and the division exists as a living memorial to Twilight's lost friends. But can Twilight handle six proteges? After all, Celestia had her hooves full with merely one.
