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.

“The Lost Mines of Karak” is the sequel to “The Shadow Rift of Umbraforge” and the fourth part of the Scales of War adventure path. After the player characters' success in "Siege of Bordrin's Watch" and "The Shadow Rift of Umbraforge", they have garnered something of a reputation in the city of Overlook. They are introduced to a wealthy patron that believes there is a connection between a shadar-kai arms dealer (from the previous two adventures) and a long lost dwarven mine. The patron wishes the PCs to find and secure the mine in order to use its wealth and resources to defend the city. The party then must travel through a wasteland and desert to find this mine. Once they have, they must fight through the hordes of monstrous creatures that inhabit it and defeat the Queen of the Drylands - a powerful naga. Pgs. 56-93

Side-Trek adventure When your PCs gain access to the teleport spell, their whole world changes. That simple spell opens up instantaneous, long-distance travel. No more long overland journeys or dangerous retreats through hostile territory. All it takes is clasped hands and a word from the wizard, and poof! The PCs are where they want to go. Except that it isn’t that simple, because teleport isn’t foolproof. The off-target teleports are a matter of scattering your PCs someplace else on the map and forcing them to get their bearings and make the long overland journey anyway. But this Side Trek focuses on the really intriguing column on the teleport chart: “similar area.”

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. The newly appointed Duke Castaril Ambrinigan has recently relocated to a modest, newly constructed keep near the frontier town of Ormanlak. He and his family arrived safely, but a caravan containing family heirlooms was waylaid by a band of frost giant raiders. Most of the items were of no consequence to the Duke, with the exception of one: a three-foot tall golden statue of a lion. The Duke, wanting to avoid a war, sent an emissary to the frost giants. He offered gems totaling 10,000 gold pieces in value as ransom for the lion. The giants accepted, and a time and place was set for the exchange. But there is more. A white dragon named Whildenstrank lives in the midst of a nearby glacier, and has maintained a network of winter wolf spies, including some in the frost giants' camp. Through these spies, Whildenstrank learned of the capture of the golden lion, and the upcoming trade. Thinking that the lion would make a fine addition to his frozen treasure hoard, Whildenstrank has prepared to strike.

Long ago, a local priest created a warded graveyard on a remote hillside. As the years passed, it gained a reputation as a spot whose defenses were powerful enough to keep undead in and tomb robbers out. Adventurers began to bring the remains of any creatures they suspected might become restless in death to the Tomb Steppe for interment, and in time they also sought aid against such creatures from the friendly priest. After his death, a brief spate of undead activity commenced, then died away once again. As the years passed, the tales of undead activity in the Tomb Steppe faded into legend, and colonists began to move into the lands nearby. The town of Night Falls was founded a short distance from the graveyard, and it grew quickly into a thriving trade center and farming community. Realizing that the Tomb Steppe was safe enough during the day, the citizens began burying their dead there rather than building new crypts on pristine farmland. Because this method of interment was cheap and easy, people from many surrounding communities brought their dead to the town as well. The business of burial brought new prosperity to Night Falls, and a guild called the Funerary House sprang up to control the trade. But it seems that the threat from the Tomb Steppe has not entirely been laid to rest. The Great Mausoleum -- the largest and finest tomb in the steppe, has been unsealed, and an apparition has been seen within. Who will go to the Tomb Steppe by night and reseal the tomb? Lest Darkness Rise is a short adventure for four 7th-level characters. In keeping with the season, it has a stronger horror theme than most D&D adventures. This scenario can be used as the climax of a series of adventures featuring its secondary characters, or it can simply be a site-based adventure that the PCs stumble across at the right moment. The scenario is set in a semi-civilized area in the far north, far from cities and churches, where winters are harsh and summers never get very hot. These inhospitable conditions have resulted in a low humanoid population. The scenario need not be set in such a wilderness; a rural farming community far from cities works just as well. The only real requirement is that the area have few settlements. The action takes place in the small town of Night Falls and a nearby necropolis of tombs, mausoleums, and graves known as the Tomb Steppe. As always, feel free to adapt the material presented here as you see fit to make it work with your campaign.

The residents of Haskenport are worried -- someone is living at the old manor house. The local druid says it's a band of hobgoblins. Are they just looking for a temporary shelter before moving on? Or do they plan to bring a whole tribe to live there when the place is secured? Or do they work for an even worse creature that no one has seen yet? Whatever their reasons for being there, the situation can't be good. It's up to the heroes to clean the monsters out of the place so the townsfolk can sell it.

Why should anyone travel the cracked cobblestones of the Old Road?

Could he be seeking revenge for the militia attacks that recently dispersed his band?

Designed as an Introduction to the world of Eberron and is intended for a party of four 1st-level characters. This adventure takes place in Sharn, the city of Towers. It begins, as many incidents in the City of Towers do, with a corpse. A warforged assassin, a mysterious blank book, and an offer from a House Cannith heir leads the adventures into the depths of Sharn--eventually to an ancient ruin dating back to before the creation of the Kingdom of Galifar. Along the way, if the adventures are successful, they recover a lost schema--a part of a pattern used by artificers to craft magic items. They also learn that many different agencies are interested in this relic, including those loyal to the various House Cannith elders and agents of the infamous Lord of Blades. Pgs. 307 - 317

Dare to defy death in this adventure for the world’s greatest roleplaying game. The talk of the streets and taverns has all been about the so-called death curse: a wasting disease afflicting everyone who’s ever been raised from the dead. Victims grow thinner and weaker each day, slowly but steadily sliding toward the death they once denied. When they finally succumb, they can’t be raised—and neither can anyone else, regardless of whether they’ve ever received that miracle in the past. Temples and scholars of divine magic are at a loss to explain a curse that has affected the entire region, and possibly the entire world. The cause is a necromantic artifact called the Soulmonger, which is located somewhere in Chult, a mysterious peninsula far to the south, ringed with mountains and choked with rainforests.

In this Adventure, the heroes explore the lair of an adult green dragon who has become a dracolich. She is served by living and undead minions and slaves. Pages 302-307
