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?

Anandak, a red dragon, has taken over an abandoned dwarven stronghold as his lair. He has also assembled together a rough confederation of monsters to act as his bodyguard. Anandak is preparing to enter into an alliance with the Black Prince, the March Lord Draven. The plan is for Anandak's monster allies to terrorize the lands north and east of Knacker Knob while the Black Prince, on pretext of marching to the aid of Knacker Knob, take control of Knacker Knob and the surrounding region. An emissary from the Black Prince, Lord Gonzaga, is currently in the dungeon, and he is in possession of papers that might reveal the Black Prince's treasonous plot. The lair is horribly overcrowded because monsters of all tribes and gangs are gathered to take counsel with the red dragon. Monsters are sleeping in the hallways because there is so little room, and the antagonism between races is at flash point. The PCs may be able to fan these resentments into intermonster battles. League of the Red Serpent is the third dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

Synopsis: A swamp village is plagued by swarms of insects; several villagers have died from it. It turns out that the local herbalist is actually a vampire who takes the form of a swarm of mosquitoes. Talk to villagers and get rumors, visit the herbalist, suffer through some dreams, get ambushed by the herbalists minions, chase him into the basement to kill him and rescue the villagers. The mosquito vampire and, maybe, the role play involved in convincing the villagers to dig up the graveyard (to find empty coffins filled with sand!) should be fun. The rest of this is pretty simple.

What no one in the village knows: Yvonne is a budding witch secretly feuding with Old Olga, an evil hag in the woods - who now demands a human sacrifice from Yvonne in return for her child. Who can sort out this mess, bring back the innocent child, prevent a murder, and return peace and quiet to Willow Creek? This adventure can also be used as a mini-campaign sandbox.

“The Temple Between” is an adventure for 9th level characters, and it is challenging enough to take them to 11th level by the time all is said and done. Although intended as the final chapter of the heroic tier portion of the Scales of War Adventure Path, it can be run as a standalone adventure, or as an adventure in a campaign of your own making, with a small degree of modification. It contains elements of urban investigation, dungeon delving, and even wartime conflict, making it a suitable adventure to players of many tastes and preferences. The western end of Elsir Vale has been greatly troubled in recent days. The threat of the orc hordes from beyond the Stonehome Mountains, though turned back at Bordrin’s Watch, still lingers in the people’s minds. Peculiar and hostile creatures of shadow lurk in the caverns and caves below. Political squabbling grows among the city’s powerful dwarf clans. All this makes the city particularly vulnerable to an enemy nobody saw coming - that nobody even imagined. This enemy has goals and objectives far beyond the ultimately unimportant Elsir Vale, but the first step is the utter subjugation of Overlook. An enemy who, at least in part, is already here. In this adventure the player characters start by investigating the strange behavior of the city's clergy. They swiftly discover hints of a conspiracy worming its way through the city hierarchy - some members are possessed while others have been replaced by dopplegangers. After trailing this conspiracy to its source they discover a portal that leads to an ancient temple in the mountains. Using the portal, the PCs go to the abandoned ancient temple where they must confront both a cadre of fey and a band of mercenaries, from whom they learn there is a plot for a full-scale invasion of the region! The PCs must them rush back to Overlook and cement their place as heroes as they face off against the invading forces. Pgs. 4-71

The renegade magic-user Bargle is wanted, dead or alive. Rumor holds that he dwells in the bowels of a nearby abandoned keep, performing all sorts of foul sorcery. Only the truly brave, or perilously foolish, would dare to challenge Bargle in his own domain. Expanded dungeon of the BECMI red box sample dungeon.

A terrible thunderstorm batters a seaside port, yet thunder and lightning are nothing compared to what is about to be unleashed by the diabolic crew of the Rabid Dawn. Casters with access to control water, control weather, or control winds will prove especially valuable, as will characters with strong Swim skills. The adventure is best suited to a predominantly good or neutral aligned party of PC's. Strike on the Rabid Dawn takes place in the port city of Hardby (Dungeon #109). As most of the action takes place within a lighthouse and on a ship at sea, however, any suitable port from your campaign makes an appropriate substitution for Hardby. Pgs. 12-32

"Orcs have returned to the once quiet border province of Blackmarch. The Bleak Tower and its meager garrison are all that stand against the tide. Their only hope lies in a ragtag band of adventurers willing to venture into the perilous maw of Ironwood Gorge..." "Ironwood Gorge is a fantasy role-playing adventure for 4-8 characters of levels 2-5, designed for older editions of the world's most popular fantasy role-playing game and its clones such as Labyrinth Lord and OSRIC. The material is also easily adaptable to any other class and level based fantasy role-playing game. Ironwood Gorge serves as part two in the Blackmarch sequence of adventures, but is built to function just as well as a one-off adventure, a drop-in-a-hex location for sandbox games, or as a kick start to a new campaign. The module includes keyed maps detailing both the Bleak Tower: a living, breathing refuge for adventurers; and Ironwood Gorge: a cave complex with over 100 keyed areas of traps, monsters and mayhem. The module is illustrated throughout with original artwork and includes appendices detailing new monsters, magic items, and spells. Whether you are looking for an out-sized adventure to usher the hardiest characters to the intermediate levels, or a fully-realized location to plunder for maps and ideas, Ironwood Gorge is a treasure from the old-school of gaming..."
