Our story begins on a lazily winding road that runs through the rolling grasslands of the Greenfields. Sundown is approaching as our protagonists top a rise and see the town of Greenest just a few short miles away. Instead of the pleasant, welcoming town they expected, they see columns of black smoke rising from burning buildings, running figures that are little more than dots at this distance, and a dark, winged shape wheeling low over the keep that rises above the center of the town: Greenest is being attacked by a dragon!
