From publisher blurb:
This adventure is for 4-6 heroes of 4th level, for a one-shot adventure for Pathfinder Second Edition. (Though this may take 1-2 sessions to complete).
The entire community of Tacaam is abuzz with the news of a recently discovered sinkhole. A rumor that the fabled City of Gold exists below is spreading like wildfire from one villager to the next. The village archeologist and her research team descended into the hole three weeks ago. Not a single member has returned to report their findings. Indeed, the only creatures emerging from the hole since its discovery are a plethora of bats.
In this level 4 adventure, the heroes will encounter vermin of all sorts, carnivorous plants, dangerous dinosaurs, and unfriendly morlocks. Although this sinkhole isn’t the location of the fabled lost city, the heroes will gain fame and goodwill among the villagers if they rescue the surviving archeologists who are held captive by morlocks in the deepest part of the cavern complex.
And if the heroes are observant, they can find a clue within the morlock camp to the actual location of Zamona, the lost City of Gold… Which is an adventure for the future!
