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 Star of Olindor is an adventure designed for 7th-level rogue, or other character of similar abilities. The obstacles in the adventure are set up to encourage the use of stealth and trickery, and many rely on classic rogue skills. The adventure takes place in the city of Cairdus, the details of which have been intentionally left imprecise, so that it can be easily slipped into an existing campaign, or better yet the adventure can be altered to take place in any existing city. Part 1 of the Olindor Trilogy.

Szass Tam, the lich lord of Thay, and his Red Wizards threaten to dominate all of the Sword Coast. The Bloodgate, an elemental node of power, must be destroyed in order to stop him. Remake of the original 4th Edition adventure.

The Underdark is a subterranean wonderland, a vast and twisted labyrinth where fear reigns. It is the home of horrific monsters that have never seen the light of day. It is here that the dark elf Gromph Baenre, Archmage of Menzoberranzan, casts a foul spell meant to ignite a magical energy that suffuses the Underdark and tears open portals to the demonic Abyss. What steps through surprises even him, and from that moment on, the insanity that pervades the Underdark escalates and threatens to shake the Forgotten Realms to its foundations. Stop the madness before it consumes you! Note for DMs: This adventure is not for the faint of hearted, to run or to play. The module starts with 10 NPCs traveling with the party through the grueling Underdark. This number can grow. The encounters within the book are often incredibly deadly for the characters that would be going through it. This is because the module expects them to run or talk their way through the events, or, in some cases, the module expects them to lose. If your players aren't the kind of party to run, talk, or surrender, do not get this adventure. The module almost requires that you use milestone leveling because the experience provided does not commonly get players to the levels they should be once they get to certain milestones in the story (7th when they leave the underdark, 15th when they face the demon lords.) Good luck and happy questing.

For years, the knights of Mendev have held back the evil locked inside the Worldwound, a vast, demon-tainted landscape. Every few years, they anoint a new protector, a sacred guardian charged with pitting his will against the teeming hordes bent on devouring the very souls of the living. This year, something has gone horribly wrong, and now a bloodthirsty demonic army has overrun the ancient fortress, and threatens to pour into the surrounding countryside.

For more than a hundred years, the demon-infested Worldwound has warred against humanity, its Abyssal armies clashing with crusaders, barbarians, mercenaries, and heroes along the border of lost Sarkoris. But when one of the magical wardstones that helps hedge the demons into their savage realm is sabotaged, the crusader city of Kenabres is attacked and devastated by the demonic hordes.

A cold winter wind blows from the Scourge Mountains, but its origins are not of this world. And with it come horrifying stories of a fey who walks the land.

It is the Winter of the Witch…and if the archfey Koliada is not stopped, it could be the world’s last. “Winter of the Witch” starts with the PCs receiving an urgent but somewhat cryptic message from the skeletal knight, Sir Keegan.

The PCs fight their way into deep ruins, defeat the demon lord’s toadies, and retrieve the Sun’s Sliver. Once the PCs have recovered the Sun's Sliver, they must confront the Winter Witch in Winter's Heart, the witch's icy sanctum in the Feywild. Only there can they confront the cold-hearted archfey and save a section of the world from a wintery doom.

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.
