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?

An interesting and atypical adventure in its writing style. For one the module contains insightful "When things go Wrong" sections and DM guidance for sticking close enough to the rails for the story and fun's sake. Lots of DM hints about how to handle PCs' choices. Overall the story is fine too - a traditional hook, a mystery, some twists. There's a tower, a surprise pocket-dimension context, and a dungeon. It's mirror of life trapping, isn't it? Well, yes and no. People go in, and they don't come out. Nor can you talk with anyone inside. Somehow, that's not quite the way you remember those mirrors work. This Skarda fellow showed up a few years ago with a band of raiders, and no one in the land has been safe since then. Whole villages have disappeared into this Skarda's mirror. Your band is approached by relatives of one of the victims?and adventurer like yourselves. You have to get into that mirror of whatever-it-is, find this man, and get him out in one piece. The reward is more that adequate. Only problem is, no one out here can tell you what to expect once you get in? or even how to get there. TSR 9188

What is the Lost Lands? The Lost Lands is the home campaign world of Necromancer Game's and Frog God Game's own Bill Webb. This campaign has been continuously running since 1977. Many of the adventures published by Necromancer Games and Frog God Games are directly inspired by this campaign. They have evolved over the decades, and more material continues to flow from it as the dice keep rolling. Sages and wizards of legend speak of the Lost Lands—many of the players who have lived and died in Bill's campaign over the years now have a place in history (in the books). Frac Cher the dwarf, Flail the Great, Bannor the Paladin, Speigle the Mage, and Helman the Halfling are well known to the fans of Bill's work. This is the game world, and these are the adventures in which the players of these famous characters lived and died. Hundreds of players over the past 35 years have experienced the thrills and terrors of this world. The Sword of Air is the centerpiece of the Lost Lands. Currently, this epic tome consists of several parts: 1. The Hel’s Temple Dungeon—kind of like Tomb of Horrors on crack. This six-level, trap-and-puzzle infested dungeon formed the basis of Bill's game through his high school and college years. Clark Peterson’s very own Bannor the Paladin spent several real life months in the place, and, sadly, finished the objective. This is where the fragments of the fabled Sword of Air can be found…perhaps. 2. The Wilderness of the Lost Lands extending to the humanoid-infested Deepfells Mountains and providing detail about the nearby Wizard’s Wall. This so-called “wall” was raised by the archmages Margon and Alycthron harnessing the Spirit of the Stoneheart Mountains to raise the land itself, creating a massive escarpment to block invaders from the Haunted Steppes. These archmages are actual player characters from the early 1980s who live on in the legends of the Lost Lands. Over 70 unique encounter areas are detailed, and each one is a mini-adventure in itself. New wilderness areas may be added based on bonus goals described below! 3. The Ruined City of Tsen. Legend has it the city was destroyed by a falling meteor. This place forms an aboveground dungeon area the size of a city, with over 100 detailed encounter areas. It’s a very dark place…even at noon. 4. The Wizard’s Feud—This campaign-style adventure pits the players in a long-running series of intrigues and battles between two archmages. Which side will they take? Their actions all play into the overall quest, and could well determine which side wins. Law and Chaos are not always what they seem, and if the wrong decisions are made, the entire ordeal could fail. Remember, one of the wizards WANTS Tsathogga to win. 5. New monsters, new demons, new spells, and new rules for various aspects of play. 6. The Tower of Bells. This dungeon is the result of the workshop Bill ran at PaizoCon 2013, where the participants assisted him in building an old-school dungeon. Visit the tower and discover the secrets of the “artist” within. Beware: those entering may never come out!

In this adventure the heroes invade Susurrus, the palace of the githyanki lich-queen and attempt to end Vlaakith's reign forever.

However, the lich-queen's spies know of Zetch'r'r's treachery and are preparing to deal with him and the PCs.

Rumors have been spreading in small towns and hamlets, regions isolated in the far reaches of the wilderness and cut off from major cities and trade routes. Rumors of strangeness in the forest, where the animals suddenly watch with intelligent eyes while the sound of a crone’s laughter pierces the veil of night. Rumors of young men and women disappearing without a trace in the wilderness. Rumors of a cottage that walks on enormous chicken legs. Rumors of Baba Yaga. Those rumors turn out to be true and the Dancing Hut of Baba Yaga has come once again to haunt, confuse, befuddle, and terrorize the far corners of the land. The Grandmother of Witches cackles in her flying mortar as she sails over the trees, a shadow in the darkness, but what does she want? Why has she come? And what strangeness awaits in her fantastic hut on dancing chicken legs? Brave heroes are needed to head out and find the answers to these questions and more! Welcome to the Dancing Hut of Baba Yaga, an adventure unlike any other. Baba Yaga, the Grandmother of Witches, has come to town, and her dangerous and mysterious Dancing Hut beckons adventurers to brave its wondrous depths. Open the doors, unlock the puzzles, and meet the famed witch, her adopted daughters, and a host of other strange characters. This module presents the Dancing Hut and its most famous owner, Baba Yaga, as an adventure site worthy of high-level exploration. You can use the module in many different ways, and the Adventures in the Hut section provides ways to entice characters to seek out Baba Yaga. In general, the adventure environments presented are designed to challenge a party of characters levels 11-16, but with some adjusting and focus on non-combat solutions, a party of lower-level characters could also explore the Dancing Hut.

"For untold eons, Eshebala ruled over Vulgarea, the 193rd Layer of the Abyss...content to revel in hedonism, corrupt the hearts of her dwindling followers and inflict petty cruelty. Yet, if there are days in the Abyss, there came one when she realized she despised her own province. She hated demonkind. She hated the Abyss. It had become unbearably tedious, spent...done. The burgeoning goddess decided she would dip her toe back into the lives of mortals, and quest to remember...to understand her own existence...But that was a lofty goal for a mind that had long ago begun to unravel. Instead...She is learning that all she has left is cruelty...and it was always cruelty that gave her power, so she now believes, to the woe of any who cross her path." Partly inspired by a scant notation by Carl Sargeant in 1992's TSR book Monster Mythology: "Eshebala is the foxwoman deity of vanity, charm, greed, and cunning. Her symbol is a female fox. Eshebala appears as a foxwoman, a shapely fur-covered female with a fox’s head, or as a beautiful young elf maiden. She is bedecked in rich clothing and jewels, and carries a silver mirror. Eshebala’s realm of Vulgarea can be found on the 193rd layer of the Abyss. She is wily and vain. She favors beautiful things and collects jewelry and art, the tackier and flashier the better. She prefers to overcome her opponents using subtlety rather than force, seducing and devouring out of boredom. She loves gossip, and always insists on being the center of attention. Eshebala is a patron of evil shapeshifters who use their wits and wiles before resorting to violence." Eshebala is a true chaotic evil demon goddess, behaving 100% true to form, and an extremely challenging opponent to take down for your players.

Horrors in the Dark The origin of the ShadowGate is lost in antiquity. Some claim it as the work of devils, others cannibal cultists or even demon lords. Not long after its discovery it was boarded up by the priests of the local church, and then fortified by paladins. Of late something has emerged from the portal. It remains trapped within the divine defences, but for how long?
