Ten days ride north of the great city, there is a small town named Treefall. Up until recently, this town was well known for its rich harvests, happy villagers, and prosperous weather. These days, however, the once-proud details from Treefall have turned darker. Instead of tales of unending prosperity, you hear hushed whispers of a great curse that has struck the once-happy village. Word has it that, where once roamed contented cattle, now strange beasts hunt by the moon's cold light and terrorize the hapless region. You have scoffed with the others at these stories. Despite the things you've seen in you adventures with your friends, the thought that such ill might befall such a sleepy town strikes you as terribly unlikely. There is plenty of evil in the world, true, but there are also much bigger and better targets. But, tonight despite the firmness of your disbelief, the stories come to find you. You have been traveling north along the roads on your own business, enjoying the rich fall colors and warm afternoons. Your camp os small and secure, with a roaring fire and meat cooking over the flame. It's one of those crisp autumn days that makes you long for a warm hearth after a long ride in the cool air. Still, the fire is good enough for now and you and your friends have a wonderful meal, talking and singing and laughing, anticipating a restful sleep beneath the blanket of stars. Until the beast attacks.

The Approaching Swarm is a short adventure for four 9th-level characters. The party can consist of any mix of classes, but it should include at least one character that is good in wilderness settings, such as a druid, ranger, or barbarian, and at least one cleric. This scenario should prove a reasonable challenge for characters from 8th to 10th level. The adventure takes place in a swampland that is near a small settlement. A band of rag-tag settlers have carved out a small settlement, called Crivdall, on the edges of a great swamp that is infamous for its terrible creatures. The area is rich with resources, and the settlers have done well hunting and foraging in the swamps. Unbeknownst to them, however, an insane druid has taken notice of their transgressions and wants them to leave. The druid, Aleretheral, is a half-orc with a curious affinity for insects and vermin. The swamp is home to numerous breeds of monstrous insects, some of which the druid has begun to breed to make them even larger and more aggressive. Through his abilities, Aleretheral has set enormous vermin onto the helpless settlers, preying on them as they venture into the swamp. With autumn rapidly coming to a close, the settlers are becoming desperate as more of their numbers are killed by hordes of marauding vermin.

Each adventure is 100% good, solid dungeon crawl, with the monsters you know, the traps you fear, and the secret doors you know must be there somewhere.

A prequel adventure for Xumoria Megadungeon. “The famed archaeologist Jonas “Greytooth” Walker discovered a strange pit upon an expedition to the Dead City.
