From publisher blurb:
Revenge in the crater is a random dungeon adventure, with both a low and high level of difficulty. The lower level is designed for a group of 4 level 2-4 characters whilst the higher level is designed for a group of 4 level 9-11 characters, with the option for some variation. Deep within the forest a pale and unearthly light has been seen between the rotten trees. The area is said to be the sight on a fallen star and the locals hunters and trappers avoid the site at all costs. In recent months to accompany the haunting light, a soft and unnerving song floats through the woods, beckoning passers by to investigate and find the mysterious source. This is an adventure made primarily for use with the 5th edition of Dungeons and Dragons but can be used for other rule systems with some tweaking.
