A group of researchers under the employ of Princess Celestia come across a very important discovery and the princess herself is called in to assist. Something has been lost in the tundra around the crystal empire.

So alone for so long a time.

He arrived in Canterlot four years ago with a sack of bits, good eyes, and a greater vision. Now he's the sixth-richest CEO in Canterlot, the third strongest Grandmaster in the Pro Magical Duelling Circuit, and the most handsome, in his personal opinion. But behind the charming smile of this Gentlepony Adventurer lies a dark secret: When not selling enchanted armours or food imported from alternate worlds in his supermarket chains and fast food stores across Equestria, the well-connected, creative, unforgiving and absolutely brilliant Unicorn known as Silver Star has been running a rather profitable side business: Donning disguises and conning the richest, stupidest, and most corrupt monsters around the world and across the multiverse out of everything they own. Sometimes, the Canterlot Police Department, the secret multiverse-mapping "Map Club", and that law firm he bought will pass the cases they deem "Impossible" to him. Other times, he seeks out his own prey, or the wounded and helpless will come to him for aid. The risk, the rush, the thrill of a good plan executed perfectly, or better yet, salvaged despite unforseen complications... It's incredible.

But when even gold loses its lustre, Silver Star - formerly Star Apple - must make new bonds, reconnect with his family, and embrace friendship. But what does it mean when feelings start to appear in a heart he had believed to be beyond even the warmest touch? And when something is traded away... is it possible to get it back?

In the heart of Ponyville, oblivious to the machinations of Canterlot in his absence, as a disaster of his own making prepares to tear Equestria asunder, Silver Star Apple is going to find out.

But those pleasant slice-of-life adventures are put on hold when a new threat to the world rises. 21 magical cards have hidden themselves around Equestria, and the underground Diamond Dog Empire isn't the only group trying to collect them. Gather them all, and none can match your power. Can Silver and his new best friends find them in time?
