Base of Operations is a short adventure intended for four 5th-level characters. DMs can easily modify the adventure to suit higher- or lower-level adventurers, or larger or smaller parties of adventurers. Simply adding a few monsters to every encounter area makes the adventure more challenging for larger parties, and adding levels to any of the humanoids can make them more of a threat to high-level groups. For low-level adventurers, make the relationship between the two factions within Brightstone Keep more strained, and take away a few monsters from each group. You can remove levels from some of the humanoids in the adventure to make it a lower-level challenge, but it is important that the orc cleric (described in encounter area 8) still have the ability to animate the dead. Still, he can have fewer minions around him when encountered, and that makes him less of a challenge for a lowlevel party.

Many centuries ago, a band of paladins fell from grace. These blackguards were defeated after a great battle and their grim fortress, the Iron Tower, was razed. A small abbey was established near the ruins, where generations of monks mixed ancient eldritch wards, mighty clockwork traps, and multiple fail safes to build the Iron Crypt of the Heretics. Three mighty vaults ensured that its evils would be sealed for all eternity. But unbeknownst to the brotherhood, their impregnable crypt had a single weakness: the very monks that had built it, for they knew its secrets. When a devourer stole into their abbey, the profane beast forced the monks to help it inside the Iron Crypt. It successfully broke into the first of three vaults, releasing an army of wights. The story of the devourer and his wight army is told in Dungeon Crawl Classics #12: The Blackguard’s Revenge. Now, in the Iron Crypt of the Heretics, the heroes must venture into a crypt designed by the world’s greatest thieves, magicians, and seers, solve its puzzles and deadly traps, and seal it once more from the outside world.

"Deeptown lies in the shadow of mountains, a town where anything is for sale if you can only meet the price. But in the wild surrounding valleys of the Deeps, it's the bandits who make the darkest deals - and their ambition comes at a cost far greater than the contents of any wayward caravan. You and your team have just been handed a new job: disrupt a meeting between a bandit lord and his mysterious new allies. At a remote mountain villa, you will strike hard and fast and leave terror in your wake. They give you the tools. You provide the talent. Survive, and you'll be well rewarded. Fail, and you'll pay the price. You've got three days to raise some hell." This was one of the first third party adventures under the OGL for 3rd edition published by Atlas Games under the Penumbra line. The attack on the mansion is not a dungeon crawl, but feels like a commando raid aided by some unique magic items.

The citizens of Phent, which is a large town in Thesk, are a proud, yet warm and accepting folk. For the past nine years, they have been host to over six hundred orcs, which is certainly an anomaly in the average Faerûnian community. In 1360 DR, Zhentil Keep sent one thousand orcs to aid in the fight against the westward-sweeping Tuigan hordes. The orcs fought well—well enough that the citizens of Thesk welcomed them as citizens when Zhentil Keep abandoned them in this land in 1363 DR. Still, a current of unsettling concern lingers. Some believe that the orcs are still part of Zhentil Keep’s strike force, but that they went on standby to wait for the moment when their masters give the signal. Once allowed, these orcs may launch a crippling attack from within. However, in nine years, no signal has been given—at least none that any of the paranoid folk have noticed. The orcs are enthusiastic citizens and, apart from some rowdiness during breaks from the mines or fields, they have hurt no one. And then, a prophet comes, with a message of war . . . In A Call to Arms, the player characters (PCs) have a chance to prevent orcs from rising up against some humans. This adventure is designed for four 9th-level D&D® characters. The encounters can be adjusted up or down to suit your group’s needs, however.

Mimic Madness is a psudeo-adventure with four interesting mimic encounters. These four encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL4 to 7. The encounters vary the mimic's tactics significantly, such as by having them we a weapon rack that wields the weapon it holds, pretending to be animated furniture using its ability to speak, and pretending to be a floor covering a pit; none of them rely on the typical chest or door mimics. Pgs. 24-25

A dark shape emerges from the shadow of Castle Ravenloft. A flash of lightning reveals the sneering countenance of Count Strahd von Zarovich. His eyes burn with eternal hunger and a contempt for life. From a narrow balcony, he peers out into the drizzling twilight at the few sad lights of the village below and mutters a single name: "Ireena..." Based on the classic adventure by Tracy and Laura Hickman, the Expedition to Castle Ravenloft campaign adventure updates the original 1st Edition "Ravenloft" module, retaining the Gothic flavor and familiar elements while expanding and reimagining some of the locations to create a deeper, richer adventure experience. This adventure is designed for characters of levels 6, bringing them up to level 10, and features a new, easy-to-use combat encounter format. This book also presents new magic items, feats, and prestige classes for player characters. For use with these Dungeons & Dragons core books: Player's Handbook, Dungeon Master's Guide, Monster Manual.

An ancient secret is discovered in an overrun border town, long ago forgotten by the elves of the east. It is a magical key—so obscure that history does not remember its form or even what it unlocks. But an unseen evil searches tirelessly, even as the lost knowledge finds its way into the most unlikely hands. The adventure contained within these pages will take a group of heroes from city to ruins, from wasteland to dungeon, and from despair to hope. It presents new creatures, spells and magic items. Published by Sovereign Press.

Trouble Cubed is a is a pseudo-adventure with three interesting gelatinous cube encounters. These three encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL5 to 7. The encounters vary the cube's encounter situation significantly, and the tactics needed to deal with them, such as by trapping a character with a portcullis between a cube and a pit trap, placing a cube half down a pit trap, and having the cube accidentally ingest a beneficial potion (such as spider climb). Pgs. 29-30

The vampire lord Gulthias, servant of the great dragon Ashardalon, has returned to the tower which was once the main cult temple of Ashardalon. The vampire prepares for the dragon's return by awakening the other cultists who had preserved themselves as undead creatures. Gulthias is a vampire and a level 13 wizard.

Note: This is a sequel to Out of Body, Out of Mind. The legend of the realm of Tirna'cel is well known. Once remembered for its power-mongering warlords, homunculi-wielding sorcerers, and archfiends from the deepest pits of the Abyss, Tirna'cel has become a powerful and welcoming land over the last 600 years, due in no small part to the efforts of the warlord Tirna'gael, a member of the land's founding nobility. But your party knows the truth. You ventured into the tomb of Tirna'gael some six months ago, and therein discovered that the fallen warlord was actually little more than his brethren: a petty, avaricious power-monger. Possessed by a rival force which also desired the kingdom - a rare incorporeal demon called a nescent, which inhabited his body and augmented his already incredible power to unforeseen levels - Tirna'gael sought to overthrow the ancient warlords only to replace them. Through Tirna'gael's augmented body, the nescent overwhelmed and eliminated the other warlords, eventually dominating the realm along. But before it could consolidate its rule and throw Tirna'cel into an even darker age, the secret of its power was discovered by the paladins of Garadon, a virtuous cell of justice and light. The paladins lured Tirna'gael into the center of his own fortress and trapped him there within a powerful anti magic field. His body withered and died but the nescent remained dormant, waiting for its chance for revenge. During your visit to Tirna'gael's fortress-tomb six months ago, you accidentally released the nescent from its prison. That enemy has since been vanquished - at least for the time being - but the memory of your pitched battle against it still lingers as you approach the original chapter house of the Order of Garadon. You have been summoned.

But the lure of the city's magical treasures still draws heroes and villains alike to tempt death—or worse. Drawn by the dream of limitless magical power, the Cult of the Dragon has carved out a secret stronghold in the heart of the ruins. Using the power of a corrupted pool of radiance, the Cultists stand poised to attain their goal of subjugating all of Faerûn... unless a group of brave heroes can stop them first.

Into the Forsaken Temple's Crypt is a short adventure for four 10th-level characters. The adventure takes place in a buried temple crypt, which has been sealed for centuries. Dungeon Masters can adjust it for higher-level characters by widening the dead magic areas and increasing the number and power of constructs and undead that inhabit the complex. The PCs have entered the Forsaken Temple's crypt and started exploring a bit. They had the opportunity to work with some drow to get past clay golems. Now they face a greater danger, but maybe they'll turn back before it's too late.

All of the Treasure, None of the Traps is an adventure that includes a single gauntlet of traps that contains twelve traps; meaning that it has either one or twelve encounters. The adventure consists of a long, twisting corridor with all of the traps set off, but these traps are reset by the PCs when they reach the center of the area. Pgs. 32-34

Kingdom of the Blind is a short adventure for four 8th-level characters. The adventure is set in a minor duchy that is fairly removed from the ruler of the land. As a result, trouble can brew in the land and the king would not know immediately. About three years ago, a medusa, Zhanna Serpentlock, began systematically turning every person in Duke Jellhyn Fedorel's (N male human Ari5) duchy to stone. After losing many peasants to the medusa, Jellhyn attempted to placate her. He offered her his second son, Dephyl, for a husband. Duke Jellhyn and his family had always been rather tense and uncomfortable around Dephyl anyway due to the fact that Dephyl had lost an eye in a freak magical explosion as a boy. Zhanna accepted the marriage, and though Dephyl didn't really care for his family due to how they treated him, he was also less than happy with the arrangement. A year ago, Zhanna appeared at Fedorel's citadel again. She claimed that Dephyl had been untrue and that she had turned him to stone for his adultery. Throwing Dephyl's stone head down in the courtyard of the citadel, she swore vengeance on all Fedorels for his betrayal. Duke Fedorel and his household fled the citadel. Rather than give chase, Zhanna took up residence there and began ruling the duchy as the sole remaining Fedorel family member. Jellhyn and his family have lived in exile for a year. This is what the PCs can learn, but more is going on. As it turns out, Dephyl is alive and quite happy with his marriage. Zhanna is not repulsed by his disfigurement as his family was, and Dephyl's missing eye is something of an asset in the relationship since it lessens his chance of being accidentally petrified by his wife. In the two years of his marriage, he has grown up and gained ambition -- he wants to rule. As a second son (pawned off on a monster), he would never have received the chance. Now, with Zhanna's help, he can rule. However, Dephyl doesn't have the stomach for killing his father and brother. Instead, he and Zhanna plotted to take over the duchy by frightening everyone away. Zhanna carved a stone bust of Dephyl and used it to frighten off the rest of his family. Now Dephyl and Zhanna live happily in the citadel and rule the duchy together, though Dephyl's existence among the living is a secret.

Kingdom of the Blind is a short adventure for four 8th-level characters. The adventure is set in a minor duchy that is fairly removed from the ruler of the land. As a result, trouble can brew in the land and the king would not know immediately. The PCs had just entered the citadel in the last episode. Are they now dealing with hauling statues or fighting angry staircases in their efforts to get to the second floor?

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. A band of rag-tag settlers have carved out a small settlement, called Crivdall, on the edges of a great swamp that is infamous for its terrible creatures. The area is rich with resources, and the settlers have done well hunting and foraging in the swamps. Unbeknownst to them, however, an insane druid has taken notice of their transgressions and wants them to leave. The druid, Aleretheral, is a half-orc with a curious affinity for insects and vermin. The swamp is home to numerous breeds of monstrous insects, some of which the druid has begun to breed to make them even larger and more aggressive. Through his abilities, Aleretheral has set enormous vermin onto the helpless settlers, preying on them as they venture into the swamp. With autumn rapidly coming to a close, the settlers are becoming desperate as more of their numbers are killed by hordes of marauding vermin.

The long-forgotten monastery to the Lord of Winds hides a secret of immense evil. The PCs are tasked with delving into the abandoned ruins and discover if two Houses are related in some way. Scales from level 4 to level 10, but originally designed for characters of 7th level. Pgs. 17-39

A wealthy sea-trader hires the PCs to solve a pirate problem and recover stolen supplies. Almost 100 pirates have made base in a treacherous cove. When the PCs arrive, most of the pirates are at sea on a mission. A large host of pirates remain in the base and force PCs to be creative with their approach, as a direct attack would be met with an overwhelming swarm of pirates. Unknown to the player's as they scheme is that the ship will soon return with its massive crew. The treasure cave is guarded by the dead sailors foolish enough to try and steal from the captain, who is the only one who can enter the cave safely. Players must be creative to deal with the pirates in the base and the approaching ship while still securing the plundered supplies in the treasure cave.

This adventure focuses on a Zhentarim attempt to spread terror in Mistledale, although it is suitable for almost any lightly settled area northwest of the Sea of Fallen Stars. "The Raiders of Galath's Roost" is suitable for four 1st-level characters, but PCs should be at least 2nd level before tackling the adventure's second half, the Zhentarim Citadel. Even in the first half of the adventure, many of the encounters are quite formidable for 1st-level characters, and the PCs might find it necessary to withdraw and recover one or more times before completely exploring the ruins.
