One page adventure, one page map. On the edge of a lake/ocean’s windswept field/forest, outside of his small stone home, a very old, callous human magic user, Cyfrin the Wrathful, summoned an invisible stalker in a magical binding circle. First he began to taunt the stalker, proclaiming his dominance over it, describing its powerlessness to do anything but carry out the old spell caster’s will. Next, Cyfrin dispelled its invisibility, ordering it to execute his plan. In Cyfrin’s excitement, he gazed upon the stalker’s now visible, horrifically impossible face - and abruptly suffered a stroke, dying on the spot. Still imprisoned, the stalker wants freedom. Will the PCs help it? Adventure hooks provided. Published by Wicked Cool Games

In times ancient, an infamous paladin-artificer named Khaldun unearthed a cursed tome bound in the flesh of the first medusa. Driven to madness by its secrets, he used the necromantic magic contained within to call forth an army of dread warriors from the Netherworld. Though his assault was devastating, he was ultimately unsuccessful, and the mightiest crusaders of the realm banished Khaldun to the Netherworld, where he would rot for eternity at the bottom of the River Dis. Unfortunately, rather than perishing in that bleak plane, Khaldun escaped his silt grave and thrived, amassing a legion of undead followers and erecting a Tomb in which he could perfect his mechanical craft without interruption. It was not long before he shed his body and became a demilich. After several centuries of scheming, the undead warriors under the command of the ‘Iron Lich’ have burst free of the Netherworld, laying waste to not only the mortal kingdoms that exiled him, but also the exalted domains of the gods themselves. The crusaders’ quest is simple – stead the Tomb and destroy the Iron Lich. Published by Defy Danger and Save Versus Death

The Siege of Castle Rend is an adventure for the fifth edition of the world’s first roleplaying game, suitable for five 5th-level characters. It takes place over four parts, and each part can be completed in one or two sessions of play, depending on your group’s playstyle and how long you like to play in a single sitting. If all goes according to plan over the course of this adventure, the player characters will expose an usurping lord, fight orcs, acquire a stronghold, defend it from an invading army, win the admiration of a town filled with potential vassals, and make political connections within the Barony of Bedegar. Of course, no adventure goes according to plan. The PCs will invariably throw these well-laid schemes into chaos, and they’ll have to improvise. But if we know how things would have gone if the PCs never showed up (or are cowards), it makes it easier for us GMs to improvise when things go off the rails. Published by MCDM

The ruined Thorp of Rhu once produced honey, apples, hard cider, and mead. Villagers now stay away as they believe Rhu is cursed. Years ago a witch, Katla, was cheated from a reward promised for chasing away an attacking giant. Furious, she waited for her chance at revenge. Over a year, Katla created many small sack dolls and gifted them to Rhu’s children. One night, each doll animated, killed the sleeping adults, and set the village on fire. Now Sorcha, the village elder, asks the PCs to go to Rhu to locate a lost dwarven friend, help a restless soul, and find out what really happened to Rhu long ago. These outsider sack doll spirits take great pleasure in tormenting and slaying weaker creatures. At Rhu, the PCs encounter murderous sack dolls, learn the villagers’ & dwarf’s fate, parlay with spirits, and clash with Bloody Tears, the witch’s minion & spirit familiar.

They say the legendary Ashes of Evensong have been found! In the year 689 DR, the song dragon Evensong was incinerated by Kallurous, a red dragon. In the wake of her death, Evensong’s ashes were gathered into a hundred urns by members of the Harpers. Originally intended as mere relics, the urns fell out of the Harpers’ possession when the caravan transporting them was ambushed. They were thereafter lost to history. Three months ago, stories began to circulate that at least one of the urns has been found. An artificer from the city of Elskar claims to have acquired some of Evensong’s ashes. According to his story the ashes are more potently magical than even residuum, created as they were from the mortal remains of a powerful magical creature burned to ash in the fires of an even more powerful dragon’s breath. This tale is dismissed by most, but certain factions and private interests aren’t willing to reject the possibility without investigation. If true, the artificer may be in possession of a highly dangerous and unfathomably valuable substance. More importantly, he may be in possession of the knowledge of where it came from, and the secret of what happened to the Ashes of Evensong all those centuries ago. In search of the truth behind a rumour that some of the Ashes of Evensong have been found, the player characters find that the Ashes are ultimately incidental to a far more worrying development. The trail of the Ashes leads them to the discovery of a fiend pact warlock operating among the ruling class of the city, a vault of forbidden magics the secrets of which have been breached, and a diabolic artefact about to be reclaimed in the name of a Duchess of Hell. With a focus on investigation, puzzles, and dangerous traps, Ashes of Evensong rewards players for caution and cleverness. Published by Spilled Ale Studios
