For the past several days, dozens of strong earthquakes have rocked the coastal area surrounding the underground Temple of Poseidon. Since the first quake, there have been a growing number of reports of strange events and macabre occurrences throughout the area. Several families near the temple have abandoned their farms and refused to return. They claim to have been terrorized by inhuman specters who prowled about their farms late at night. One of the farmers says he found a farm animal crucified and eviscerated in a ritualistic fashion on his front porch. Following the first tremors, all communications with the Temple of Poseidon, seemingly the center of the troubled area, were cut off. Messengers dispatched to the temple to request guidance from the Holy Oracle located there have not returned. Now the darkness has spread to this town. Unnatural births have occurred. Strange cries can be heard in the night, and there is a cowl around the moon. Magical divining has proven useless in naming the dark forces that invade. Many of the townspeople have already abandoned their homes and those who remain have but one recourse left: They have sent out a cry for hardened adventurers, experienced in dispatching evil. They must travel to the temple to discover the fate of the men there, and, if possible, elicit their help in destroying the growing heinous power. Pgs. 31-46

Once every decade, the tides of the Empyrean Ocean recede far enough to reveal the highest eaves of a mysterious undersea tower. Long ago this was an eldritch fastness of Sezrekan the Elder, the most wicked wizard ever to plague the Known World, but now the tower is known simply as the final resting place of the fabled Black Pearl – an artifact rumored to bring doom upon all who dare to posses it. Tonight the moon nearly fills the sky, and the tides have already begun to recede. Adventurers have eight short hours to explore the tower before the dark waters return. The fabled Black Pearl will be theirs for the taking…if they can survive the Pearl’s curse.

The party is caught between warring goblin and kobold gangs, occupying an abandoned dwarven mine. Will the heroes ally with one of the sides in this quarrel, try to make peace between old enemies, attempt to eliminate both sides, or achieve their goal stealthily and unnoticed? The choice is completely theirs! Small Party Adventure: Though the party size of 3–5 characters is considered optimal in D&D, there are times when you can only gather one or two players at most. This adventure is designed exactly for such occasions.

A deathpriest hierophant of Orcus has turned the lower catacombs of a cemetery into a base for the undead and demonic horde it is gathering. The deathpriest loses control, however, with the arrival of a balor, and its carefully orchestrated forays to snatch victims have turned into wholesale slaughters. The PCs arrive in a nearby town to meet with a merchant who promised to sell them a long-coveted magic item. They are not altogether pleased to arrive to find the aftermath of a brutal attack—and no sign of their item. Pgs. 150-155

Introduction No frills, here. No fancy charts and tables. No art to dazzle your eyes. Just a crawl; that happens to have a bit of a background, and a (group)death-dealing Bad Ass! waiting for the characters. How you run it is your business. What you delete, exchange out/in or modify is up to you. You can be as kind and patient with the players as you like, or let the chips fall (dice roll) where they may. You can allow pre-rolled characters, provide pre-gens yourself, or let the players bring their own, favorite character they have worked hard to get to the levels indicated; remind them, if the latter, that character-death is part of the game! I issue only the following comment: if run as it is laid out , it is nearly certain that at least one character, and as many as all of them, might die during the adventure.

In this adventure, designed to last for a 3-4 hour session, the player characters encounter (or are directed to) a mysterious object in the mountains: A strange, silvery disc around one hundred feet across. If they make it past the deadly laser turrets and the very hungry sole survivor who lurks inside the only viable entry, they can explore the derelict craft. They will find several magic items, including a solar-powered laser pistol, as well as evidence of the ship's dead masters: The brain-eating illithid. But with technology comes other ways to stay alive over long periods of time, and the greatest danger is accessed by pushing the only lit button in the entire ship...

Local villagers whisper of a mysterious place deep in the marsh - a place shrouded in mist and dotted with barrow mounds, ruined columns, and standing stones.

"For Blibdoolpoolp!!" "The power of the mind and belief are wonderous, often leading us to manifest things that aren’t real. For the kuo-toa, this power is heightened, allowing their collective belief to manifest gods." Two tendays ago, a paladin of Torm was kidnapped by kuo-toa. In a strange turn of events, she was mistaken for a kuo-toa god, and whisked off to their underground lair. Barria has managed to pose as the god and now shakily leads a small faction of kuo-toa while trapped underground. With her influence being increasingly scrutinized, and with the different kuo-toa sects on the brink of civil war, it’s a dangerous time, even for a ‘god’… The heroes’ mission — rescue the paladin from the kuo-toa oceanic lair before she’s transformed into a kuo-toa god.

Within the muck and darkness of a cave off in the forest lies an ancient creature. A manifestation of evil and psychosis that causes even devils and demons to turn a blind eye. This monstrosity is known as The Gol'Goroth. Rumors say it has just sockets where there should be eyes, yet it sees everything in this world and in others. It pierces the veil of the mind and inflicts madness on all who come near . . . of course these are surely just rumors. Surely just an excuse to justify the actions of a twisted cult that is ravaging local villages. Surely this is just the manifestation of their crazed minds as they carve their own bones into weapon and slice their own flesh to ribbons - all in the name of the Gol'Goroth

About: This encounter was cooked up in the Write your First Encounter workshop by the Storytelling Collective.

Helena is being held captive by the Schaefer family, trade rivals rumored to have ties to the underworld. Elize has been unable to free her sister herself because of her identical appearance.
