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 adventurers have located the secret lair of Aleretheral, an insane half-orc druid with mastery over vermin. He has been breeding and training monstrous vermin to defend his territory. With the adventurers invading his home, he will do anything he can to protect it.

Only the howling of the wind fills the midnight air. The master of Castle Ravenloft is having guests for dinner—and you are invited. Spans levels 1-10.

For over a thousand years the things that lurk beneath the waters, skulk in the darkness and lie hungrily in dank crypts have been patient, while all around them men and monsters bicker amongst themselves, bold enough to traverse the dark caverns' depths but afraid or perhaps wise enough to leave the forgotten vaults and hidden passages alone. Beneath the lost ruins of ancient Thracia lie the vast caverns of a once great civilization. While a death cult rules the surface, the Minotaur King and his beast men lurk fall below.

Using it as a home base, a party can make forays into the surrounding wilderness, encountering monster and marauder alike. The centerpiece of the adventure is certainly the CAVES OF CHAOS, a network of tunnels and caverns found in the walls of a nearby but isolated ravine.

Through combat and negotiation, the players can try to explore and map out these caves, perhaps with the aim of accumulating valuable treasure or even cleansing the land of evil creatures. However, even the Caves are not all they seem. Beyond the goblins and kobolds lurk dark horrors: cults dedicated to fiendish chaos and a Minotaur's enchanted labyrinth await the unprepared adventurer.

"The creatures are just too intelligent, too crafty, and too strategy-minded to "rampage." Rampaging brings the wrath of oath-bound knights, powerful mages, and divinely-protected priests. Why would a dragon want such attention, unless it had some special secret, or unless it was insane? Or both. The northern reaches of the Derideth Swamp were once plagued by a rampaging dragon. This black dragon, named Storamere, took a mad glee in attacking human villages, wiping out orc camps, driving off the lizardfolk, and decimating farmland. He met his untimely end, though, in an ambush devised by the monks of the Order of St. Chausle. Storamere died with a curse upon his draconic tongue: "you could not have defeated me in my lair," he told his slayers. "I am forever invincible in my lair." Now Storamere is back, with a horde of his misshapen half-dragon offspring, to have his vengeance. All that remains of the once-heroic monks are two old men driven mad by their last encounter with the black dragon, so it falls to a band of adventurers to again defeat the mighty dragon -- this time in his palace, where the boastful Storamere claims he is at his strongest." Includes maps and damage rules for navigating Storamere's lair, a semi-solid palace made of a dangerous, corrosive liquid five feet thick and located on the ethereal plane. Most of the monsters in the lair have the Half-Dragon template applied. Published by Atlas Games
