The Shattered Heroes of Myste Cryk

Publisher's blurb: A party of successful NPC adventurers have returned to their home village of Myste Cryk to retire in peace. Unfortunately, a villain they recently crossed marches towards Myste Cryk with a legion of undead, bent on the destruction of everything the heroes love. Even worse, the NPCs hate each other. A major falling out means there's no organized effort to defend the villagers from what now looks like certain doom. Can the player characters bring the Heroes of Myste Cryk back together again in time to save the villagers from a terrible demise?
