A TiM: The Truth in Meanings inspired fanfiction.

Four years after the Protectors of Equestria gave up the elements of harmony to defeat Tirek. Equestria had never experienced such bliss. The ponies continued to innovate and grow, an air of love and friendship in the air and under the protection of the princesses. Such peace was not a permanent event, however; Chaos will continue to pursue, death will continue to follow, and love will be lost.

Such event will lead to the birth of impossible made possible by sheer will alone. Perhaps there was more to the events that led to Twilight Sparkle's admission under Celestia's tutelage?
