Only fools, madmen, and adventuring parties go into the Malpheggi, the swamp beyond the Everfree Forest. It can be left as an exercise for the reader as to which of these categories Samus Marcus (a Thyatian swordsman, or so he says) and Ivan (his companion in trouble) fall into. When they are rescued by the registered adventuring party, the Elements of Harmony, a grand quest across the D&D world of Mystara begins. Together they face culture shock, international politics, romance, dungeons, and a dragon with a grudge as Marcus learns how to trust his new friends and make up for his past mistakes while the Elements of Harmony try to save Equestria from a threat which proves more... complicated... than they originally thought. Also, pie. And hats. A D&D (Mystara)/MLP Crossover.

Inspired by the heroics of the mysterious mare known as the Stable Dweller, Silver Storm, a guard of the town of Marefort, decides to go on a daring mission to rescue her captured brother. Of course things rarely go as planned and her attempts at heroism drags her into a tangled web of plots and conspiracies as warring factions vie for control over the last great city: Dise.
