A fallen clock tower holds components from an ancient artifact. Upon discovery of the components, competing agents look to launch expeditions to uncover additional components scattered across distant places—and times. The now-lost Temple of Moloch and the construction site of the legendary Tomb of Horrors are two of those locations. However great the risks, finding the components demands the effort, for whoever does so can reassemble the fabled Infernal Machine of Lum the Mad!

In the aftermath of AD&D Second Edition's "Return to the Tomb of Horrors," the demilich Acererak was thought destroyed. In truth, his spirit lingered and now after eons he schemes once more to achieve divinity. The characters must travel to three extraplanar dungeons, in addition to the remains of the original Tomb, in order to stop this from coming to pass.

The PCs have traveled to the Nine Hells to confront an outpost of devils responsible for slave raids on their homeland. In this realm of burning ash and fire-streaked skies, the infernal legions prepare constantly for war. Pgs. 138-143

As the very fate of the world is being shaped, only the strongest heroes can shatter the diabolical plan. "Lord of the Iron Fortress" is a stand-alone adventure for the Dungeons & Dragons game, the seventh adventure in a series of eight designed to take players from the beginner to advanced levels of play (although no other adventures need be played to play this one).

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.

When Fort Iron was taken from the duergar who inhabited it, much of their subterranean quarters were never fully explored. An ancient oubliette has been discovered and its contents have disturbed the miners. Can the mine and the miners be saved from the dangers of the Oubliette of Fort Iron?

"More than five hundred years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share a rich mine in a wondrous cavern known as Wave Echo Cave. In addition to its mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (called the Forge of Spells), where magic items could be crafted. Times were good, and the nearby human town of Phandalin (pronounced fan-duh-lin) prospered as well. But then disaster struck when orcs swept through the North and laid waste to all in their path. A powerful force of orcs reinforced by evil mercenary wizards attacked wave echo cave to seize its riches and magic treasures. Human wizards fought alongside their dwarf and gnome allies to defend the Forge of Spells, and the ensuing spell battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost. For centuries, rumours of buried riches have attracted treasure seekers and opportunists to the area around Phandalin, but no one has ever succeeded in locating the lost mine. In recent years, people have resettled the area. Phandalin is now a rough-and-tumble frontier town. More important, the Rockseeker brothers - a trio of dwarves - have discovered the entrance to Wave Echo Cave, and they intend to reopen the mines. Unfortunately for the Rockseekers, they are not the only ones interested in Wave Echo Cave. A mysterious villain known as the Black Spider controls a network of bandit gangs and goblin tribes in the area, and his agents have followed the Rockseekers to their prize. Now the Black Spider wants Wave Echo Cave for himself, and he is taking steps to make sure no one else knows where it is." Extra Info from AL.com users: by @marcellarius. "There are a variety of locations in this adventure: the town of Phandalin, a gang hideout, a ruined keep in the forest, a destroyed village, and Wave Echo Cave (a dungeon crawl). The adventure is written in a sandbox style and relies on the players to choose their path. Phandalin offers several side-quests which could serve as hooks for continuing adventures. The premade characters have ties in their backgrounds to NPCs and locations. If you're not using these you'll need to consider other ways to introduce key NPCs."

"And they bade their slaves, 'Build unto us tombs to rival the palaces of the gods, for there shall we live or lives and sleep our deaths in splendor.' And the people of Maru-Qet wore their fingers down, broke their backs, burst their hearts to obey. Indeed they raised up great tombs to rival the palaces of the gods. And their masters were well pleased, for it was as gods they saw themselves." The brown dragon Urum-Shar lurks in a strange tomb, plotting schemes only a wyrm of incredible power could understand. Expanding on content from Draconomicon: Chromatic Dragons, this adventure takes the heroes into Urum-Shar’s dark and trap-filled lair, where they will eventually face the powerful dragon herself. The dungeon heavily employs the use of traps, with fewer monsters. The upper tomb consists of a great puzzle of twelve rooms, and the lower tomb contains the dreaded Urum-Shar, an ancient brown dragon and heir to the lost draconic empire of Maru-Qet. The dungeon has special protections against scrying and other divinations, as well as teleportation. Pgs. 55-90

Though small, Seawell is a prosperous trading town with a good location on the coast. Next to it is a long peninsula that features mostly swamplike terrain. The inhabitants of this peninsula include tribes of lizardfolk, plus several kinds of reptiles and amphibians. Most of these creatures don't bother the town, and Seawell's militia is experienced at repulsing raids by the more aggressive lizardfolk. A large reef extends the entire length of the peninsula on the side away from Seawell. This great wall of coral is a favorite site for fishermen, but it has always presented a serious hazard to ships approaching from that direction. Thus, about 45 years ago, the people of Seawell built a lighthouse on a small promontory near the reef, about 200 yards from the shoreline. Operated by a family that lived inside it, this lighthouse ensured that ships could easily steer clear of the reef. A few weeks ago, ships stopped arriving from that direction. Three ships are now overdue, and the people of Seawell have begun to suspect foul play. Thus far, however, they have not been able to investigate because of increased raiding by the lizardfolk. Something has stirred them up, and the town militia has been too busy repulsing raids to mount an expedition to the reef. Wreck Ashore is a short D&D adventure for four 1st level player characters (PCs). The scenario takes place on and around a swampy peninsula that juts out from a longer stretch of coastline. Along one side of this peninsula stretches a dangerous reef. Just offshore on the reef side stands a lighthouse built to warn ships of the danger. At the base of the peninsula on the side away from the reef is a small port town called Seawell.

Important: The adventure is 1e but it has monster conversion notes for D&D 4th edition The town of Highport, once a human community overlooking Wooly Bay from its perch on the northern coast of the Pomarj, fell prey to hordes of humanoids swarming out of the jungle-covered hills surrounding the settlement. Though the orcs, goblins, kobolds, ogres, and gnolls razed much of the place in their ferocious rampages, the smoldering ruins they left behind soon became a new kind of community, a place of trade between the humanoid “locals” and the unsavory human traders who have no compunction about doing business with them. Slaves are a commodity in ready supply in Highport’s market, since many pirates raid up and down the coast of the bay, putting fishing villages to the torch and filling their holds with captured refugees. Slavery has become a thriving business in the town, and rumors abound of a cartel of Slave Lords who run things from behind the scenes, filling their coffers in secret from the buying and selling of human chattel. The trade has become so prolific that the good folk to the north have grown tired of these depredations and decided to fight back. Forces of righteousness and honor have recently descended upon Highport, some openly and others in secret, in various attempts to destroy the machinations of the Slave Lords and abolish the abominable enterprise that has taken far too many loved ones from home and hearth. One such doughty servant of goodness is Mikaro Valasteen, a cleric of Trithereon. Mikaro slipped unnoticed past the crumbling walls of Highport with a single mission: to rescue and transport as many slaves to their freedom as possible. Mikaro and a handful of faithful assistants located a number of escaped slaves—as well as rescued a few more not sufficiently restrained and guarded—and shepherded them through the gates and beyond the reach of their humanoid tormentors, returning them to their lands and homes. This covert freedom brigade enjoyed remarkable success early on, since the servants of the Slave Lords were often lax in their vigilance and sloppy in their efforts to prevent loss of the “merchandise.” After one too many shipments never made its destination, the humanoids stepped up their security and the normal channels of escape from Highport closed to Mikaro and his team. He cannot risk exposure by smuggling the freed slaves through the gates as merchandise any longer, since shipments of goods are now regularly stopped and checked. No longer able to free the slaves in that manner, Mikaro began hiding his charges in an abandoned villa in a particularly rundown part of the town. Although they are safe for the moment, their numbers have grown unmanageable, and the priest fears it is only a matter of time before someone slips up and brings slavers to their doorstep. Ever more desperate to find a new means of escape from Highport, Mikaro has started work on a plan that is both daring and dangerous. He intends to use a series of old sewers coupled with natural caverns running beneath the town as an escape route to the sea beyond the walls. But he needs someone to clear out the creatures and pitfalls he knows lie within. Pgs. 2-27

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 story thus far, the PCs have been tasked by Duke Ambrinigan, a local lord, to recover a stolen statue of a golden lion. The lion was stolen in transit by frost giant raiders, and was to be ransomed back to the Duke for 10,000 gp. The PCs were sent to perform the exchange. The giants, however, were attacked by the white dragon Whildenstrank, who stole the statue and retreated to his lair in the middle of a nearby glacier. The PCs encountered the remaining giants, and then set off westward toward the dragon's lair. They traveled across the flat part of the glacier, encountering the frost giant ranger Velg the Dragon Tamer, as well as some burrowing bulettes. Then they braved the hazards of frost worms and remorhaz in the Ice Canyons: a maze of twisting passageways surrounding the black spire of rock that the dragon calls home. The PCs now stand at the edge of an open space, looking at the towering edifice in front of them.

The blade charges the PCs to undertake a dangerous mission to an abandoned githzerai fortress in order to perform a ritual to awaken the blade's true form. Along the way, they must deal with bounty hunters hired by an old enemy (from "Shadow Rifts of Umbraforge"), and confront a vile gang of gnolls terrorizing Elsir Vale. Pgs. 14-54
