Time, it is the one thing that connects all the worlds together, as it is the one thing that all of them have in common. The Quartz, a place where time itself resides, but what happens when this place is disrupted? A young unicorn will soon find out, called by an ancient power older than time itself. A being of Wisdom taxed with the protection of not only Equestria, but everything in existence.
