Fan Casting My Little Pony: Chapter 3

A few months after the events of "Chapter 2", Twilight suffers from PTSD from the Canterlot Invasion, which she suppresses by burying herself in her studies and recovery efforts. However, she is forced to place her own recovery process on hold when a thought-be long-lost kingdom known as the Crystal Empire resurfaces after more than a thousand years ago. Aided by allies both old and new, Twilight must reconcile her past demons and confront her present ones to save the Crystal Empire.
