Emerald Mist, an illusionist unicorn born and raised in Manehattan, has been on a journey for several months. Searching for a certain pony, he ends up passing through the quaint town of Ponyville. What he didn't expect, however, was how much this town would change things for him. Namely, the rediscovery of an old friend he hadn't seen in years, Applejack. Seeing her again relindles old feelings in him, and he finds himself unwilling to leave.

The biggest change to his life, however, comes soon after. One awakening triggers others, and later that very same day Jade Mist emerges within him. Now having to share a mind with Jade, who claims to be a part of Emerald and vice versa, life is about to get a lot more complicated for him.

It won't be long before Emerald and Jade will have to come to face with things they've been running from. Things that could potentially ruin whatever happiness they can achieve. Their past, both remembered and forgotten, is catching up with them.
