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.

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?

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.
