Feasting at Lanterngeist. A Feast of Horror!
It looks like a simple harvest festival in an unremarkable village turns horribly, terribly wrong. In a way things can only do when adventurers are involved. A simple disappearance threatens to become a massacre as a hidden menace long slumbering in the bogs prepares to burst forth in the midst of this rustic revel. Will your heroes be able to thwart this menace, or will they too become a part of ravening doom that is this feasting?
Feasting at Lanterngeist is a 5th Edition adventure for 9th to 10th-level characters. It can be easily inserted into any campaign with a hint of cosmic horror in the background, or to introduce a bit of horror when your heroes might have become a bit complacent.
