In Dragon 200, Ed Greenwood mentions an NPC named Sumbral the Mystical in the adventure "The Whistling Skeleton". In 1996 Roger E. Moore mentioned him as Realmslore, as a pre-lich version of Sumbral. Does anyone know where I can find more information on him? I just ran my gaming party through "The Whistling Skeleton" and they really don't like loose ends, nor do they enjoy a visage of a face following them around, so they want to take him on.
Now plugging away on mass conversion to 5e, as well as my imprint J. Halk Games.
