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.

From The Magazine: "Every summer, Duke Hightower holds a competition quite different from the traditional jousting and archery tournaments held by similar lords of his station. The rules of his tournament change from year to year, and, to oversee the games, the duke has appointed two wizard brothers who help choose the setting and create the rules and challenges of the competition. This year the competition is called the “Owlbear Run,” an overland race that requires each participating team to escort a live owlbear from the town of Telvorn to the town of Milvorn. The teams will face a variety of challenges; some are devised by the wizards, others by the competing teams or their sponsors, and some occur entirely at random. All of these tests are in addition to the challenges inherent in motivating a temperamental owlbear. Fortune and fame await the first team to cross the finish line, and the local lords sponsoring the race are eager to enlist skilled champions for their causes." Pgs. 2-27
