Having put down a rising of giants, it was discovered that the motivating force behind their depredations was that of long-forgotten evil - the Dark Elves. Determined to seek out these creatures, a body of doughty adventurers mounted an expedition to learn the strength of the Drow and bring retribution to them (DUNGEON MODULE D1, DESCENT INTO THE DEPTHS OF THE EARTH). This module contains background information, a large-scale referee's map with a matching partial map for players, referee's notes, special exploration and encounter pieces, a large map detailing a temple complex area, encounter and map matrix keys, and an additional section pertaining to a pair of unique new creatures for use with this module and the game as a whole. A complete setting for play of ADVANCED DUNGEONS & DRAGONS is contained herein. This module can be played alone, as the second part of a series of three modules (with DESCENT INTO THE DEPTHS OF THE EARTH, D1, and VAULT OF THE DROW, D3), or as the fourth part of a continuing scenario (DUNGEON MODULES G1, G2, G3, D1, D2, D3, and Q1, QUEEN OF THE DEMONWEB PITS).

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

When an ill-favored orb drops from the sky and devastates the countryside, only the PCs stand between an ambitious wizard, a cult of dragons, and a dark ambition that could bring an army of fiendish wyrms into your campaign world! "The screams became overpowered by the sound of the terrible falling star--a black orb of malign energy hurled from the firmament in the dead of night. In that instant, the village of Rhale was utterly destroyed, reduced to a hollow crater of flaming decay. Now, frightened talk of a dark presence descended from above has taken root, though none can put name to the faceless fear that might reside within this terrible orb." While traveling the countryside, the player characters witness an explosive event - the falling of a meteor into a distant hillside. Soon thereafter, they encounter several mercenaries menacing some refugees. From them, the PCs can learn, that a group of dragon worshippers called the Black Covenant are in the area and intend to use the fallen star for their own nefarious purposes. Upon arriving at the crater, the PCs find that the falling star is in fact a massive sphere of iron with an opening in its side. They enter the sphere to find a small complex of rooms protected by numerous traps and guardians. They also battle several members of the Black Covenant, until they make their way to the heart of the complex, where they discover the source of the Covenant's interest in the Black Egg, they try to use it to create a half-fiend red dragon. The PCs must succeed if they wish to prevent the creation of an army of fiendish dragons.

The adventure takes players from a town devastated by an unexpected flood, through a drowned land where nature is turned upside down and desperate families cling to the roofs of their ruined homes, hiding from the monstrous products of a disordered world, through the strange tomb of an ancient race, to a profundal zone, hidden for millennia and now exposed, and finally to the Observatory itself, an eerie abandoned treasure palace, where they will encounter a pale and unexpected terror which will seek to claim their lives. The adventure is suitable for a lucky mid-range party, a stupid high-level party or an exceedingly clever low level party. It is difficult, with a meaningful possibility of character death. Should you find them, and defeat their guardians, the treasures of an ancient culture will be yours. At the final point of the Observatory is a glimpse of another world.

For the past 5 years this elven village has been plagued by undead creatures of the nearby swampland. The undead are consisted of unlucky elf villagers or travelers who were foolish enough to walk through the swampland.

For as far back in time as the tales of history stretch, the area bordering what is now the Lands of Launewt has been a foreboding, practically impenetrable forest.

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.

Adventurers explore a frozen, buried dungeon of long-dead giants that turns out to be the birthplace of Runemagic itself, and may still hold the secrets of that forgotten art. However, even if they do survive the extreme cold and unfriendly denizens, they will still have to face the massive Runeforged Guardian before they can escape. This adventure includes lots of interesting multi-part traps and alternate encounters that can be added or swapped out in several places.

THE NEXT MARCH WASN'T DUE FOR ANOTHER 189 YEARS. TRY TELLING THAT TO THE MODRONS! On a regular schedule, the Great Modron March spills out of Mechanus, and the lawful automatons files their way around the Great Ring. No one knows why they do it, but everyone stays out of their way - because when the modrons march, they'll walk right over a berk who doesn't know enough to move aside. But this March has started decades before it was supposed to begin, and that's even more of a mystery. Caught unprepared, the planes shudder under the modrons' collective footsteps - and even the modrons themselves seem a little out of sorts. The Great Modron March anthology features 11 adventures for characters ranging from 1st to 10th level, as well as new information about the modrons of Mechanus. Each adventure can be played separely or linked together to form an extended campaign. The modron procession touches every Outer Plane in turn - and it isn't always welcome. On their unswerving path, the clockwork creatures will destroy celestial towns, be attacked by evil knights intent on using modron parts in foul experiments, and lead characters onto the deadly plains of the Abyss and into the famous prime-material labyrinth of Undermountain. Without help, they'll be lost in the swirling chaos of Limbo or even fail to complete the March entirely. And along their route, every blood on the planes seeks the answer to the most important question: Why have the Modrons abandoned their normal, lawful schedule to march years before they're due?
