There is just one thing he needs, meat for his feast.

This adventure takes place in the Moonsea of Faerûn. The players have been brought to Melvaunt to search for the missing scions of the city's great families. To the north, in Thar the orc tribes converge on the ruined fortress of Xul-Jarak, flocking to the banner of a charismatic warlord. There, he intends to sacrifice the scions of the great families of Melvaunt in a bloodritual to Gruumsh. The players will escape Melvaunt, search along the wilderness of Thar for the Fortress of Xul-Jarak, and then explore the dungeons of the ruined fortress and hopefully rescue the scions before they are sacrificed. There also is a Web Enhancement by Eric Cagle on the archives of wizards of the coast's website designed to scale the adventure to level 8. For example, it replaces the Owlbear with a Tyrannosaurus. This is an easy to scale adventure with much of the player's difficulty coming from intelligently avoiding problems, choosing how to approach each floor in the most tactical way, and quickly adjusting when something goes wrong. The adventure has sidebars including common orc battle cries (In Orc!), ready to use orc names, weather and random encounter table in Thar, a description of what happens if the party fails or partially succeeds, and suggested minis for each of the encounters. There is even an extended description of the bloodspear ritual, an event the party is not meant to encounter in a normal run. The appendix is detailed for all the humanoid characters including the scions and their equipment, the named villains, and variety of unnamed orcs the party will encounter. The fortress also offers an opportunity to introduce the players to the Underdark and the Zhentil Keep. There is a passage to the Underdark the players can accidentally explore, and return to later. Emissaries from Zhentil Keep have come to watch the ritual and have their own motivations. These npcs provide an opportunity for exposition and role playing at a point which otherwise might be combat heavy, acting as a valve for the first floor - helping or hurting the party with subtle magic should the difficulty be off.

A storm of unparalleled fury has been ravaging the peaks of the Earthspur Mountains for a tenday, and the Monastery of the Yellow Rose sits in its eye for now.

Can you brave the elements and convince the monks to escape?

The Sea of Fallen Stars connects the eastern and western sides of Faerûn. Many nations that border shorelines along its vast expanse also maintain major navies and trade fleets. A plethora of creatures and humanoid races typically found in the ocean depths live there, including sahuagin, sea elves, merfolk, and locathah. This is a story about what happens when a normally peaceful species is pushed to the point of open conflict. As elemental forces threaten the safety of the nearby locathah communities, heroes rise from among their number to strike back and defend their homes and families. Locathah Rising is a DUNGEONS & DRAGONS adventure designed for 9th-level characters.

A Giant Ransom is a short adventure for four 11th-level characters. There are opportunities for diplomacy, stealth, and combat, based on the choices the PCs make, so any mix of classes is appropriate. The adventure can be set in any campaign world, in a frontier region near glacier-covered mountains. In the first episode, the PCs were employed by Duke Ambrinigan to exchange a ransom of 10,000 gp in gems for a golden lion that was taken by frost giants in a recent raid. While waiting for the giants to arrive at the designated meeting place, the PCs watched as the white dragon Whildenstrank attacked the giants and then flew off with the statue. Charged with returning the golden lion statue at all costs, the PCs move to investigate the site of the battle.

The hobgoblins were not the only forces that remained after Kalarel was slain. Before the Keep’s portal was fully sealed, evil spirits from the Shadowfell escaped into the Nentir Vale. They were drawn to Kalarel’s own dark soul, which remained in the mortal world thanks to a spirit-orb the priest had created to prevent him from moving on after death. The presence of these malignant spirits caught the attention of a frost witch called the Rime Mistress and her followers—unaligned territorial beasts—who rose up to defend their domain. The Rime Mistress knows that the spirits present a greater threat than the hobgoblins do, so she and Prang, the Iron Gauntlet leader, have agreed to an uneasy truce. Thus, the hobgoblins and the creatures of the Cairngorm Peaks are united in their struggle against Kalarel’s spirit army.

Many years ago, Evard came to Duponde to destroy his rival Vontarin, a powerful wizard who lived in a manor at the edge of town. The two mages met near the walls of the abbey of St. Avarthil and dueled all night long with black spells, laying the old monastery in ruins with their magic. In the morning, the surviving friars found Evard dead in the wreckage and buried him in the town’s graveyard. Vontarin was never seen again. Now, almost fifty years after his death, Evard’s final curse is about to descend on the town and everyone within it. Also available in Dungeon Magazine #219 Pgs. 30-90

Despite the bitter cold that reigns here nine months of the year, the Timberway Forest has long been a source of prosperity for civilized folk who live nearby. Many trappers and hunters spend the better part of the year within its borders, stockpiling furs and meat to trade in the frontier towns to the south, where they spend their winters. Most feel that the value of these commodities makes braving the Timberway Forest worth the risk. Recently, though, a small group of trappers and hunters has awakened a terrible new menace in the forest. Based in a remote hunter's abode called the Bluerock Lodge, they hunted the animals of the woods more out of a deep-seated desire to be cruel than a need to feed themselves. In particular, they focused their hateful attention on the local Timberway lion population. Timberway lions are rather small (more like leopards), but they are known for being lithe and wary. Still, the trappers had the advantage of intelligence and tools, and before long they had slaughtered the entire pride save for its leader. As the winter worsened and game grew ever more scarce, this last surviving lion began to starve. At that point, the darker forces of nature took notice, and the Timberway Forest gained a predator like no other. Frozen Whispers is a short D&D adventure for four 3rd-level player characters (PCs). The scenario is set mostly in and near a remote hunter’s lodge in a snowy forest. The scenario can be placed in any cold area of your campaign world that features a remote tract of woodland—a copse of trees near the arctic circle, a swath of taiga near the treeline on a high mountainside, or even a normally temperate forest caught in the grip of an unnaturally snowy winter. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.
