Castos claims to be the scion of the noble family which ruled Misthollow and built the castle generations ago.

The last of his line, Baron Paytro NeMoren has left his dark secret sealed for decades in the family's underground vault. Now, years after his death, a group of stalwart heroes has gathered according to the baron's final wishes. At last, the seal will be broken and the secrets of the vault revealed. Can all sins be forgiven? The adventure is designed to kick-off a campaign, as it provides for an interesting way to get the party together. Instead of meeting at a tavern or being recruited by the local militia, each party member starts with a key to the NeMoren's vault, a key that was handed down by a friend or given as a gift for some good deed peformed in the past. The executor of the estate has gathered together all of the key-holders so that they could claim the contents of the vault. The vault can only be opened with all of the keys in unison. The vault is protected by a number of minor traps and tricks, but it also became the final resting place for the Baron's ex-lover, Lisette, and her brothers--all three of whom had attempted to blackmail the Baron. They were buried alive and are now undead. To complicate matters, a young umber hulk made its way to the vault, leaving some crude tunnels that were later exploited by hobgoblins coming from another surface entrance. The party will need to deal with the hobgoblins, the undead, the traps, and possibly the young umber hulk. There is a side-plot of poisoned groundwater in the nearby town that the party can also resolve by clearing out the undead and properly disposing of the putrid corpses leaking into the groundwater from the vault.

Goblins have returned to the area of Westgate, seeking an ancient magical item constructed for their foul kind. In their search, the goblins attack an imperial convoy secretly disguised as a merchant’s wagon. The knowledge that goblins are near must be kept quiet from the public, thus a small band of adventurers is required to seek out the creatures and the stolen magic item, deep inside the warrens of the great goblin chief! But the adventure does not end there...

"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

The ruined Thorp of Rhu once produced honey, apples, hard cider, and mead. Villagers now stay away as they believe Rhu is cursed. Years ago a witch, Katla, was cheated from a reward promised for chasing away an attacking giant. Furious, she waited for her chance at revenge. Over a year, Katla created many small sack dolls and gifted them to Rhu’s children. One night, each doll animated, killed the sleeping adults, and set the village on fire. Now Sorcha, the village elder, asks the PCs to go to Rhu to locate a lost dwarven friend, help a restless soul, and find out what really happened to Rhu long ago. These outsider sack doll spirits take great pleasure in tormenting and slaying weaker creatures. At Rhu, the PCs encounter murderous sack dolls, learn the villagers’ & dwarf’s fate, parlay with spirits, and clash with Bloody Tears, the witch’s minion & spirit familiar.
