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.

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!

"Mysterious Ways" is a D&D adventure set in the Holy Land (Israel and Jordan) during the time of the Crusades (1114 A.D.) in an alternate-Earth setting. This is a world where the portals to otherworldly realms, particularly the Lower Planes, are closed--sealed shut by the power of the True Cross, a holy relic sought by evil thieves who would see the gates to the Lower Planes flung open. Magic exists in this alternate world, but it is less prevalent than in other D&D campaign settings. This paucity of magic serves the core of the adventure's storyline and should be preserved, if possible. This adventure is designed for a party of four 7th-level player characters (PCs). It is recommended that the party include at least one lawful cleric or paladin. Consult the "Adapting the Adventure" sidebar for ways to incorporate the adventure into generic D&D campaigns and modify it for higher or lower levels of play.

Nearly 100 years ago, Lord Eriador wrested the lands from the hands of evil and began a reign of unsurpassed courage, wisdom, and might that lasted over three centuries. One day this great man of valor was called onward to continue his battle for freedom and goodness on a higher plane of existence. Leaving the responsibilities of rulership to his faithful overseer, he donned his magical shield, helm, and sword and traveled to the Holy Maountain of Anduin to meet his destiny. Eriador left the overseer with this solemn promise: if there ever arose a time of great need, he would answer a summons from the Mountain of Anduin to come back to vanquish any evil that dared to oppress his people. It is now the reign of the third overseer. For years now, an evil mage has been plaguing the land by sending forth hordes of evil humanoid minions to oppress the people. The overseer has been forced to pay tribute to the mage to protect his people. Life has become nearly unbearable for his subjects.

A fortnight ago, your party was gathered in a secret council chamber to meet with the overseer himself. You felt a spark of hope for the people of this land as the overseer told the legendary tale of Eriador. He gave you the equipment you need and charged your party with the task of venturing into the heart of the now monster-infested Mountain of Anduin to call back the people's great hero, Eriador the Paladin. Although the three parties sent before you had not returned, ridding the of the land of the mage seemed worth any risk, and you eagerly set out on your quest. Now, standing before the defiled mountain, you wonder if perhaps you were too hasty.

The battles of the Blood War have raged for longer than mortals have known life, the conflict's savagery and hatred fueling the dreams, desires and obsessions of the multiverse. One way or another, the war spills through all the layers of existence, and little escapes its influence. Some clashes have consequences that shake the Lower Planes. Others are far less meaningful - they're fought solely for the sake of violence and killing. "The Field of Nettles" is set in the aftermath of an especially pointless battle. The adventure rips the player characters from their comfortable lives and thrusts them into the Blood War full force. The goal is to cross one of the more infamous battlefields, seeing the scope and the power of the fighting - and hopefully coming away with a greater understanding of just how big the Blood War is. The adventure is designed for a party of 4-6 PCs of 5th-8th level. The characters don't get to save the multiverse, nor do they find the key to unlock the dark of any great secrets. But they might come to realize their importance (or lack of it) in the scheme of things. On the fickle borders of the planes, that can be worth almost as much.

She ran. Where to or for how long, she really couldn't say. The little flame of her oil lamp sputtered and went out a few times. She'd snap her fingers and make the wick flare to life, but she may as well have ran blind. The hallways were pitch black with soot and choked with smoke, every turn was a guess and every corridor a gamble. Unnatural screams echoed from every direction. Left, right, left again, was this the south or north end of the labyrinth? She had no idea. The next turn brought her face to face with a doorway completely consumed in blue fire. The room beyond was so bright she had to look through her fingers at it. A shadow covered her, a shape in the doorway: a hulking creature with a wolf-shaped muzzle and enormous pincers for hands, wreathed in the same blue flames. The screams were getting closer behind her, too. They had her cornered, again. The demon slammed its shoulders through the narrow opening, splintering the wood and stone. She dropped the lantern and let the wand in her sleeve fall into her waiting hand. With a word of power and a gesture, she appeared in the familiar bedroom: stuffy and reeking of wood smoke. She'd have to try again tomorrow, if she could remember.
