But now, sordid disappearances haunt the Piazza dei Rospi, while the Literators’ Guild and Barbers’ Guild wage a bloody turf war for the surrounding streets.

In an age obscured by mist and memory, Sir Galen the Brave and his knights struck down the Drake of Crestmoor with steel and flame. But as the years turned, and the heroes returned to dust, their deeds faded into myth. Doubt lurked where awe once dwelled, and in time, the bards sang of lesser deeds. In the hollows of the wilderness, the stones of their forgotten tomb crumbled beneath ivy and shadow. The Cursed Knights of Crestmoor is a short dungeon crawl for four characters of levels 1-2 using Shadowdark RPG ©. The adventure is designed to be easy to run for new game masters. Players should not be cavalier in their approach to this dungeon. There are threats in the tomb which could easily kill foolhardy player characters. Long ago a band of knights led by Sir Galen slew the black dragon known as the Drake of Crestmoor - a malevolent creature whose true name was Morghast the Black. With his dying breath, the dragon cursed Galen and his friends that they would never find rest in death. Today, the once well-kept tomb has fallen into ruin. Some time ago a band of kobolds moved into the subterranean mausoleum and began using it as a base of operations. More recently, a lizardfolk shaman named Kall’eth and his warband arrived and took over, pressing the kobolds into their service. Kall’eth came to Galen’s tomb to recover the knight’s Fireblade - a sword of dwarvish make used to slay Morghast long ago. The tomb is crawling with kobolds, lizardfolk, and the restless husks of Galen and his compatriots. A magic sword, a missing wedding ring, and plenty of adventure await you in…The Cursed Knights of Crestmoor!
