Shade Haven is a newly founded desert frontier town, home to thrill seekers, fortune finders, and a seasonal influx of hunters who seek valuable jackalope antlers. However, an ancient and nearly omniscient evil lurks beneath the desert sands, waiting to devour everything. Only the party can thwart the evil and save the town. Monster at the End of the Nightmare is a horror-themed desert adventure for a 3rd level party in the Fifth Edition of the world's greatest roleplaying game featuring art from Paweł Parol, Dean Spencer, Rob Greyvenstein, and Shane Collins. This module can be used to run and adventure or mined to create a complex and fully detailed town loaded with complex NPCs who all have their own secrets and plot hooks.
