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 Giants are on the March! The Rise of the Runelords Adventure Path continues! Driven to battle by a maniacal warlord, the once-peaceful stone giants of the Storval Plateau threaten to destroy the sleepy town of Sandpoint. Will fast action and quick wits be enough to save the defenseless community? Yet, even if the giants' initial raid can be repelled, only by striking at the heart of their titanic war machine—the black-towered fortress of Jorgenfist—can the menace be quelled. But who knows what mysterious bloodlust spurs the usually peaceful giants to war, or what mysteries lie beneath their ancient fortress?

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

Nanfield is an island village of over 50 NPCs with mysteries plaguing both its present and its past. It contains a unique ecosystem and economy and a ship full of friendly pirates that will invite you by for dinner after accidentally attacking your party.

A storm caused the PCs' vessel to sink and is now forcing them to seek shelter in the keep on the remote isle. Their goal is to locate a boat or some other means of transportation to return to the mainland after the storm has passed. But first, they must survive the tests and traps the island's inhabitants have set for them. Pgs. 45-64

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.
