Come read this revolutionary piece of fanfiction!

Finieous Fingers, the worlds greatest thief (so he says) has been offered a job by the princess of friendship. defeat the evil wizard Kask, who already has bad blood with our hero due to some stuff in the original storyline of the dragonmag comic, and his army of both ponified (side effect of entering equestria in most cases,) and not ponified, Orcs, goblins, kobolds, and other cliched fantasy monsters.
