Few planes possess the raw malevolence of the Infinite Layers of the Abyss. It is a place of random violence, appalling cruelty, and pure, unadulterated wickedness. Here, unreasoning malice rules, and countless demons torture and murder for the joy of it. The Abyss is innovative in its wretchedness, with each fleeting moment birthing new and awful psychotic acts of utter evil. Those who brave its depths find no relief from its corrosive nature, nor respite from the cancerous seeds of evil blooming within all who tarry here; they find only anguish, pain and if they're lucky, sudden, abrupt death.

Eternally does the Lord of Nessus scheme, and his designs are for all eternity; In the pit of Hell do the devils teem round his throne, and his reign is unchallenged; By the eight Dark Ones is he held supreme, and his name (speak it not!) is Asmodeus. - From "The Canticle of Thumis," 142:15 To some, justice is more important than glory, duty is more important than desire, and goodness is more important than life. The great paladin Klysandral was such a man. But even the sleep of death, at the end of a long lifetime spent battling evil, did not bring peace to Klysandral. During his funeral, the entire Temple of Neheod was dragged by terrible magic into the Nine Hells, along with the soul of Klysandral and scores of living mourners! What unearthly motive could be behind this tragedy? Only the bravest, strongest, and most resolute heroes will have the mettle to find the answer. Along the way, they will meet the enigmatic wizard Emirikil the Chaotic, sail aboard the fiendish ship Demonwing, and finally face the horrific minions and overwhelming terrors of Hell itself. Only the path of light can lead the bravest of the brave into perdition and safely out again. Step wisely, and walk in justice.

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?
