A short Pathfinder Roleplaying Game compatible adventure for 3rd-level PCs by Creighton Broadhurst
Months ago, the necromancer Dunstan Wymer was gored by a wereboar and infected with lycanthropy. Almost driven insane by the realisation of what he had become after awaking amid the gore and viscera of his companions’ eviscerated corpses, he has since shunned civilisation instead seeking only solitude and the company of his undead servants. Terrified of the savage, bloody deeds he performs when the full moon shines down upon the world he now lurks within the remote hermitage at Clear Pool. In a desperate attempt to control his terrible, atavistic urges he has taken to stealing cattle from a nearby village to assuage his bestial lust for fresh, bloody flesh. The unknowing villagers, however, are angry at the continued theft of their livestock and the arrival of a passing band of adventurers gives them the perfect tools to bring the culprit to justice...
Gibbous Moon is a short, flavoursome adventure designed to be completed in a single 4-5 hour session that features opportunities for both roleplaying and combat. The action essentially takes place in single self-contained dungeon complex and is very easy to plug into a home campaign.
