Called by the Elder Elemental Eye to serve, four corrupt prophets have risen from the depths of anonymity to claim mighty weapons with direct links to the power of the elemental princes. Each of these prophets has assembled a cadre of cultists and creatures to serve them in the construction of four elemental temples of lethal design. It is up to adventurers from heroic factions such as the Emerald Enclave and the Order of the Gauntlet to discover where the true power of each prophet lay, and dismantle it before it comes boiling up to obliterate the Realms.

A mysterious adventurer stumbles into an inn in the night, looking for an escort to the nearest temple. Before the night is over, he inexplicably disappears, leaving a trail of corruption leading into the nearby woods as packs of twisted forest creatures emerge to plague travellers. Pgs. 83-89

Shrouded in whispered rumors, Crow’s Rest Island has been avoided as long as any can remember. Nothing but death, and the memories of those long gone, greet any who take to land upon the isle’s shores. It is to this island that the PCs will find themselves driven as a storm threatens to drive their ship below the waves. Awaiting the PCs are far more than ghost stories upon this island, for there lives a very real threat, hiding here among the legends that keep sailors at bay.

"Ribbons of blood dance through the air, tracing wide crimson arcs before fraying into thousands upon thousands of bright red droplets. The cheerful tavern atmosphere evaporates in a moment, rent apart by screams and cries. A woman with grey hair stands near the bar, grasping at the dagger in her throat with fingers made slippery by blood. She sways and collapses. More screams. A man stands before her. He is holding the hilt of the dagger, but lets it slip from a gory hand as the woman falls. He freezes for a moment, then spins and sprints away, knocking aside people as he goes. A young, flaxen-haired woman at the back of the tavern cries out, “Stop him! Stop him!” as he approaches the entrance – the entrance where you and your comrades are standing. What do you do?"

The annual Winterflower Festival & Dance is just around the corner! What originally started as a festival to honor the rare Winterflower has grown into an annual gathering for families, soldiers, and hunters to eat, drink, and dance the night away. The festival is named after the rarest flower in the world. It thrives in a cold mountainous region and has a reputation for growing on sheer mountain peaks and cliffs. It is the only flower known to grow through layers of snow in order to reach the sunlight. When carefully transplanted near the village the Winterflower is considered a blessing which protects the village from harm. It is customary for the men of the village to ask the women to the dance by presenting them with rare, difficult to obtain gifts. A woman will usually select from the men based on the rarity of the gift with which she was presented. This year, a beautiful maiden by the name of Gwendolyn has come of age and many men vie for her attention. Three such men are Nicoli Vrodle, Alem Dulgra, and Vladimir Pelchonal- all of which are willing to go to great lengths to attend the Winterflower Festival & Dance with the maiden Gwendolyn on their arm. Each of the three men hire the PCs to retrieve the rarest gifts in the land. The catch? The Winterflower Festival starts in just 5 days so the PCs must hurry!

Far below the Fields of Petrichor is a vast cavern containing the skeletal remains of a long-dead Sonorous Titan, a whale-like beast that once floated through the skies of a lost age. Amongst the bones are ravines and grottos home to bizarre creatures and lost treasures that are as beautiful and valuable as they are deadly. Ghostly shapes swim through the air.

God of Ore by Tom Knauss is a 3rd-level adventure that takes the PCs from the quiet, mountainside town of Miners’ Refuge into the heart of the Stoneheart Mountains in pursuit of a failed pilgrimage to discover a phony religious relic deep inside legendary Mithral Mountain. The dark, twisting tunnels that bore into the fabled mountain soon reveal that some mysteries are not what they first appear to be. Between a Rock and a Charred Place by Tom Knauss (for 4 to 6 characters of 7th level) The characters will be thrust into the middle of an epic confrontation between the dwarves of the Stoneheart Mountains and the hobgoblins just beyond their borders. Under their new leadership, the hobgoblin warmongers deploy an innovative grand strategy: to forge an alliance with one of the dwarves’ old enemies and a traitor in their foes’ midst. The dwarves’ dominance over the region and very survival hangs in the balance if the characters cannot thwart the monsters’ ambitious plans. The Covered Bridge by Kevin Wright (for 4 to 6 characters of 4th to 6th level) Are the characters up to the challenge of solving the centuries-old murder of a historic hero? Within the adventure, the characters are caught up in the haunted memories of the ghostly knight and help him to accomplish his heroic deeds. While doing so, the party becomes familiar with his world and the murder suspects, picking up clues to their motivations and actions along the way. At the end of the adventure, an enraged spirit confronts the characters and demands that they name his killer. If they can do it, they are richly rewarded; both in treasure and the knowledge that they let a good man finally find rest. If they fail, they must face the chilling wrath of the deathless phantom. The Hunter’s Game by Tom Knauss (for 4 to 6 characters of 4th level) This adventure will find the characters traveling into the foreboding Dyrgalas Fens, a temperate swamp in the Harwood Forest nestled between the Wolf Hills and Low Hills. Dyrgalas Fens is overrun by an eclectic collection of malevolent monsters, xenophobic humanoids, and foul beasts. When some of the region’s finest gentlemen and ladies never return from their excursions to the Answin Hunting Lodge, the characters must investigate their mysterious disappearances. The journey leads them into the figurative heart of darkness, taking them not only deeper into the dreadful Dyrgalas, but also plunging them into the harrowing abyss of hatred and greed. The Missing Pin by Alex Kammer is a 2nd-level adventure designed for 4 to 6 characters. In the Lost Lands setting it takes place in the Unclaimed Lands north of the Borderland Provinces at the point where the Great Amrin River meets the Glimmrill Run. At the confluence of the Great Amrin and Glimmrill Run rivers sits the small town of Gumspur, a small backwater town known only for its convenient location and its only real export, pottery. So, when an audacious theft victimizes one of the leading families of Gumspur, a group more capable than the local constabulary is needed. On its surface, what looks to be a simple theft conceals a much deeper and much more dangerous conspiracy. In the Time of Shardfall by Michael Curtis (for 4 to 6 characters of 5th to 6th level) In this open “seek and destroy” adventure, a relic from the prehistoric past — a mystical prison containing a powerful proto-dragon and other creatures from long ago — has been flung forward in time to arrive at the characters’ current era. The prison, an enchanted pane of obsidian called the Akaata, fractures upon arrival, breaking into several shards that fall to the land below. Soon, the prehistoric menaces trapped within wander out of their broken prison to threaten the realm. The characters must search for the five shards and destroy them and their former prisoners, then confront the now-free proto-dragon before it recovers its full strength. War of Shadows by Tom Knauss (for 4 to 6 characters of 8th level) This adventure can pick up where Between a Rock and a Charred Place left off or stand on its own. Erod Flan weathered the dark folk’s storm, yet the conspirators are not done. Their focus now turns to the critical outpost of Tyr Whin. The characters and the outnumbered defenders must somehow stop the hobgoblin warlord, Grugdour, and his army from overrunning the citadel and opening a beachhead for invasion into the Stoneheart Mountains. A Little Knowledge by Tom Knauss (for 4 to 6 characters of 5th level) This module takes the characters across the Stoneheart Mountains onto the forbidding Feirgotha Plateau to investigate the myths and tales surrounding the ancient and presumably deserted Library of Arcady. The PCs soon discover that the venerable building is not as abandoned as originally believed, and its unusual caretaker keeps more terrible secrets than any of its fabled lost writings. Awakenings by Steve Winter (for 3 to 5 characters from 1st to 3rd level) Strange things occur after a meteor streaks overhead in the night sky. Combining elements of a fairy tale with elements of cosmic horror, the characters will confront a community of these evolved animals with evil plans that involve finding the fallen star and confronting an unknown entity. Cave of Iron by Steve Winter (for 4 to 8 characters from 2nd and 4th level) When a wagon train fails to return from a supply run, the characters must investigate what happened to them and the riders that were dispatched to find them. The Desperation of Ivy by Lance Hawvermale (for 4 to 6 characters from 4th and 7th level) A once-imposing residence called Coltherstone Hold was abandoned years ago, and in the decades since, a fantastic amount of vegetation has grown up the walls and rooftops, covering the structure. Many of the plants are dangerous — deadly, even — and reclaiming the hold will require more than just a few machetes to chop down some weeds. Much worse, a few of the plant specimens possess intelligence as well as an undo degree of malevolence. They’ve infested a nearby village — all but burying it in overgrowth — and have absorbed a few villagers along the way. Fishers of Men by Tom Knauss (for 4 to 6 characters of 6th level) The Dragonmarsh Lowlands is a forsaken land blighted by the vile demon lord Tsathogga and countless foul denizens. When Quaywright Fishery inexplicably falls silent, it takes those of stout heart to determine what dire fate befell the former inhabitants and what monstrosity now lords in their place. The grisly carnage leaves even the most seasoned adventurers shaken to the core, as they witness firsthand and may personally experience what it feels like when the tables turn against humanity. Forgive and Regret by Tom Knauss (for 4 to 6 characters of 8th level) The sins that stained the blighted Wytch Bog more than two centuries ago still linger as the villain who perpetrated a genocidal act longs to free his tortured soul from his undead bonds. In his warped mind, only more violence can garner his freedom, placing the innocent descendants of his long-deceased conspirators — and an entire region — in his crosshairs. A Midnight Council of Quail by Lance Hawvermale (for 4 to 6 characters from 3rd and 5th level) The characters explore a village to locate the lair of a monstrous murderer — but the villagers don’t want the murderer to be discovered. The Archdruid Cadrryn is so old and mystical that his very presence often affects the natural world around him. Over the years, his close association with the region’s quail population has bestowed upon the birds a sentience uncommon to normal avians. With slightly advanced intelligence, the quail now act as local sentinels, reporting back to Cadrryn on all matters that transpire in his domain. But the druid has been away for more than a fortnight on business of the Druidic Order of Oescreheit, leaving the quail to decide on important events without his wise hand to guide them. When the birds learn that a sinister force has infiltrated the nearby village of Eorls Gedreas, where many of them roost upon the thatched rooftops, the quail convene to determine a way to fight back. Nightstone Keep by Ed Greenwood (for 4 to 6 characters from 4th and 6th level) This location-based adventure is centered on a ruined, long-disused stone keep in a temperate wild forest area (possibly not far off a caravan road or forest trail). The characters will be able to explore the ruins of the keep, which have become a plant colony, and attempt to wrest a powerful treasure from the clutches of the araunglyd, a gigantic sentient fungus. The araunglyd will attempt to thwart the players at every turn, using its drone-like minions to harass and hinder them as they go. Pictures at an Exhibition by Dr. Dennis Sustare (for 4 to 6 characters from 4th and 6th level) This adventure takes the characters on an exotic cruise in a parallel reality known as “the Real World”. During a stopover, they find themselves on a museum tour where the vivid paintings draw them into a world of fantasy. Also available for Pathfinder and Swords & Wizardry

Wise rogues join the government, where their larceny has the cover of “legality” and the cash comes in heaps and piles from deceitful receipts and pocketed procurements rather than in small, bloodstained purses from breaking windows, scaling walls, and risking traps and long-fanged guard dogs. Wise rogues do not, by choice, go up against towering giants armed with clubs larger than the tallest rogue in the guild. Nor do they try to nick treasure from dragons without a group of powerful fellow adventurers behind them, who can hurl mighty spells, hack and hew toe to toe with an angry wyrm, heal the injured, and (when things go as they usually do), resurrect the dead. There are wise rogues, and then there are player characters. Emeralds of Highfang awaits them with open arms, offering special challenges and rewards to rogue characters—but as always, the prospects are much better for a party of adventurers from a variety of classes, with wide skills and experience, and of high level. Some might find that a broad base of experience is not only helpful, but essential for survival.

It is Autumn. Most of the clans of the Great Valley have departed south with the herd animals they depend on for survival. But one small clan lags behind. For seven nights they have been unable to travel, plagued by a terrible monster known as the Night Thing, which has killed their people and wounded more. Your party answers the call of dwarf chieftain Skarna Two-Axe, begging hunters from neighboring clans to pursue and kill the monster that’s been attacking her clan, and that slayed her son. Starting at the chieftain’s clanfire, the characters uncover mysteries about the creature that can only be fully solved by tracking the awful Night Thing to its lair, which is full of frightening apparitions. As the party ventures deeper into the Night Thing's lair, they'll discover an even deeper menace, and a plot to overthrow the chieftain. Only they can save Skarna and her people from the grim machinations of their powerful enemies! Published by Atlas Games
