From the introduction to Fortress, Tomb, and Tower: "The valley of Freestead was once green and pleasant, and the humans and dwarves who lived there revered their leader, Duke Vadarin. He was bethrothed to the beautiful Lady Kylenne the Courageous, who arrived in Freestead on the back of a white dragon. On the day before their wedding, an explosion engulfed the Palace, and almost overnight the valley fell into ruin. An adventure for characters of level 2-4."
