Trial by Fire

The Ancient Wyrm Stirs
This adventure takes the magi to yet another corner of Mythic Europe: Flanders, a medieval center of flourishing trade and the arts. With a mighty dragon as the chief adversary, this adventure will prove a challenge for even the most powerful of magi; and yet the less experienced, too, may have a chance at success - if they can prove their worth through guile and diplomacy!
