A Four-Hour Adventure for 11th – 16th Level Characters

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. The characters attempted to cross back through the swamp to their base of operations. Along the way, they may have got stuck in mud and probably were attacked by a variety of flying insects. They arrive just a bit too late to stop a massacre that occurred back at Crivdall -- the fort is ruined and it appears that almost everyone is dead or missing. Aleretheral, an insane half-orc druid who has mastery of vermin and insects, attacked Crivdall with his insects. He has often infiltrated Crivdall by posing as a harmless elf hermit who lives in the wood. In reality, he wants the settlers destroyed and out of his swamp.

Kingdom of the Blind is a short adventure for four 8th-level characters. The adventure is set in a minor duchy that is fairly removed from the ruler of the land. As a result, trouble can brew in the land and the king would not know immediately. About three years ago, a medusa, Zhanna Serpentlock, began systematically turning every person in Duke Jellhyn Fedorel's (N male human Ari5) duchy to stone. After losing many peasants to the medusa, Jellhyn attempted to placate her. He offered her his second son, Dephyl, for a husband. Duke Jellhyn and his family had always been rather tense and uncomfortable around Dephyl anyway due to the fact that Dephyl had lost an eye in a freak magical explosion as a boy. Zhanna accepted the marriage, and though Dephyl didn't really care for his family due to how they treated him, he was also less than happy with the arrangement. A year ago, Zhanna appeared at Fedorel's citadel again. She claimed that Dephyl had been untrue and that she had turned him to stone for his adultery. Throwing Dephyl's stone head down in the courtyard of the citadel, she swore vengeance on all Fedorels for his betrayal. Duke Fedorel and his household fled the citadel. Rather than give chase, Zhanna took up residence there and began ruling the duchy as the sole remaining Fedorel family member. Jellhyn and his family have lived in exile for a year. This is what the PCs can learn, but more is going on. As it turns out, Dephyl is alive and quite happy with his marriage. Zhanna is not repulsed by his disfigurement as his family was, and Dephyl's missing eye is something of an asset in the relationship since it lessens his chance of being accidentally petrified by his wife. In the two years of his marriage, he has grown up and gained ambition -- he wants to rule. As a second son (pawned off on a monster), he would never have received the chance. Now, with Zhanna's help, he can rule. However, Dephyl doesn't have the stomach for killing his father and brother. Instead, he and Zhanna plotted to take over the duchy by frightening everyone away. Zhanna carved a stone bust of Dephyl and used it to frighten off the rest of his family. Now Dephyl and Zhanna live happily in the citadel and rule the duchy together, though Dephyl's existence among the living is a secret.

Despite what some may think, those in Zhentil Keep haven't forgotten about their orc troops in Phent. In public discussion in Zhentil Keep, the leaders of the Zhentilar, the military branch of Zhentil Keep, have confidently asserted that the orcs in Thesk are completely loyal to Zhentil Keep. They maintain that the orcs are just biding their time and building up trust among the citizens, until the appointed time when the word is given. In private, these same leaders are gravely concerned. The leaders didn't get to positions of command by being idiots, and they know that the orcs are treated well and accepted in Thesk, which is a rarity for them with the humans and humanoids of Faerûn in general. The leaders know that many of the orcs would be reluctant to destroy the source of this acceptance. But what if the orcs' chief god, Gruumsh, told them to? The Zhentilar turned to the Black Network and presented the problem. The Zhents knew what to do. The Zhents have dispatched a powerful cleric, a master of persuasion and deception, to pose as an orc prophet of Gruumsh and whip the orcs into a destructive frenzy. In addition, the Zhentilar have staged raids against human caravans by what look like orc warriors so that they can start antiorc sentiment among the population of Thesk. Twin Oaks is a tiny, sleepy little thorp located just within the sheltering eaves of a great forest. Home to an extended family clan of farmers and woodcutters, the community was founded within living memory and since its creation the inhabitants have known only peace and prosperity. But just as the gentle breezes of late summer can transform rapidly into the deadly storms of autumn, dark times have come suddenly to Twin Oaks, in the person of Deskryn, a vampire who finds himself on the run from deadly enemies. Just two nights ago, as the good folk of Twin Oaks prepared for the annual harvest, Deskryn’s castle home was invaded by an intrepid band of adventurers led by a noble paladin. Although the party did not achieve its goal of slaying the vampire himself, they managed to drive him from his lair and force him to flee into the night with only the barest fraction of his former resources in tow. Unfortunately for the good folk of Twin Oaks, theirs was the community onto which the 2 vampire stumbled first, and it is here that the fiends have taken refuge. The little settlement offers the displaced vampire all that he needs: shelter from the hateful light of the sun, a selection of new servants, and a supply of fresh mortal blood. Even in his current condition, Deskryn alone is more than a match for the nhabitants of the thorp; but his best hope of survival lies not in conquest, but in secrecy. He plans to hide in Twin Oaks until he believes it safe to leave; then, he can begin plotting his revenge on the hateful paladin and her compatriots who brought him to this lowly state. As for the citizens of the thorp, they are all but helpless in the face of this powerful enemy. The vampire has already slaked his unholy thirst on one of their number, and his minions have taken hostages to ensure that the inhabitants do as they are told. All the folk of Twin Oaks hope that Deskryn will take what he wants and then leave them in peace, but few of them believe that such hopes are realistic. Until Deskryn has satisfied himself that the coast is clear, Twin Oaks—and its people—belong to him.

Trouble Cubed is a is a pseudo-adventure with three interesting gelatinous cube encounters. These three encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL5 to 7. The encounters vary the cube's encounter situation significantly, and the tactics needed to deal with them, such as by trapping a character with a portcullis between a cube and a pit trap, placing a cube half down a pit trap, and having the cube accidentally ingest a beneficial potion (such as spider climb).
