Impossible Experiments is a series of adventures, each spanning 1-2 levels. Each volume can be run individually or combined into an ongoing series. This volume establishes the premise of this series… When the wizard-king Nex retreated into his Refuge over 4,000 years ago, speculation ran rampant as to what he would do in this space. At first, many assumed that he was restrategizing for the war with Geb, but as the decades and centuries ground on, wilder hypotheses were offered. One explanation claimed that Nex was experimenting to develop a new generation of magical warriors, spies, and minions whose presence would overwhelmingly tip the scales of war against Geb, and likely other nations to follow. In recent years, the gates to the Refuge of Nex have opened, and strange creatures have emerged. Indeed, these creatures are prototypes that Nex is evaluating. Near the iruxi-founded town of Gitna, one of Nex’s first prototypes has emerged and begun to claim victims. The guard has been raised in Gitna, and the heroes are now called to fulfill their oath to defend the town by helping one of its behir guardians, recently injured in his own fight... This adventure includes two archetypes, a versatile heritage, backgrounds, and items you can offer to your players to make this adventure your own!

"The creatures are just too intelligent, too crafty, and too strategy-minded to "rampage." Rampaging brings the wrath of oath-bound knights, powerful mages, and divinely-protected priests. Why would a dragon want such attention, unless it had some special secret, or unless it was insane? Or both. The northern reaches of the Derideth Swamp were once plagued by a rampaging dragon. This black dragon, named Storamere, took a mad glee in attacking human villages, wiping out orc camps, driving off the lizardfolk, and decimating farmland. He met his untimely end, though, in an ambush devised by the monks of the Order of St. Chausle. Storamere died with a curse upon his draconic tongue: "you could not have defeated me in my lair," he told his slayers. "I am forever invincible in my lair." Now Storamere is back, with a horde of his misshapen half-dragon offspring, to have his vengeance. All that remains of the once-heroic monks are two old men driven mad by their last encounter with the black dragon, so it falls to a band of adventurers to again defeat the mighty dragon -- this time in his palace, where the boastful Storamere claims he is at his strongest." Includes maps and damage rules for navigating Storamere's lair, a semi-solid palace made of a dangerous, corrosive liquid five feet thick and located on the ethereal plane. Most of the monsters in the lair have the Half-Dragon template applied. Published by Atlas Games

The Dysmal Swamp is a coastal wetland that stretches over 100 square miles. Devoid of any urbanization, the ecosystem enjoyed its dank sanctuary. A community of bullywugs called the swamp home for generations, hunting and maintaining the balance of the land. The land also appealed to the Belange Company, a wicked fey-run enterprise making cheap magic items, who needed a secluded location far from both thieves and oversight. When the Belange Company established their magical workshop in the swamp, the bullywugs attempted to drive them off. However, the Belange Company’s supply of magical items provided enough firepower to protect their endeavor, and many bullywugs fell in the initial conflicts. The Belange Company began crafting scores of magical items to be sold across the region, using a cheap alchemical process that produced a nasty liquid byproduct glowing with chaotic magical energies. Rather than devise a new process, the Director decided to discharge the waste into the swamp. As production increased, so did the pollution, and the sludge began to warp the wetland. The region’s typically reclusive bungisngis population became aggressive. It is only a matter of time before these mutated swamp giants lay waste to bullywugs.

The town of Sandpoint, Varisia, Inner Sea Region has put out a bounty on the nearby tribe of Licktoad Goblins in retribution for the goblins raiding traders and travelers near the quiet town. The party takes up the bounty and ventures into the swamp; eventually finding the goblin village in ruins and it's inhabitants scared in it's burned huts. The party finds out; either through investigation of the ruins or the goblins themselves; that a group of skeletons with eastern arms and armor had ransacked the village and took a stash of fireworks that the goblins stole from an old shipwreck. The party then makes it to this cave and finds it empty except for a half dozen skeletons. Further in past the skeletons is their leader, a skeletal samurai who fights the party in an attempt to defend his treasure. The treasure turns out to be a letter that reveals that secrets of the Kaijitsu family; the same family their good friend Ameiko who runs the Rusty Dragon inn belongs to; that lies in wait in the abandoned town of Brinewall to the northern boarder of Varisia. Ameiko along with several other important NPCs with a caravan north. It's recommended that GMs create encounters for the caravan trip north as it's essentially 3 weeks of travel with nothing in it. It's also recommended that GMs completely ignore caravan rules; they're not flushed out and they're not fun to run. The party and the caravan reaches the abandoned town of Brinewall where their friend Ameiko becomes possessed and is thrown into a coma; where the other NPCs agree to take care of her while the party explores the town and castle. The castle is a three floor behemoth of a dungeon populated by Dire Corbies, Troglodytes, and various other monsters all under the leadership of Kikonu, an Yamabushi Tengu Oni. The goal of exploring Brinewall Castle is to find the two keys to the vault; one of which is on the Yamabushi Tengu while the other is on a Half-Fiend Decapus that lives in the basement of Brinewall. Once the PCs enter the vault they find the Amatatsu Seal; one of the seals that cement authority to one of the ruling houses in Minkai of Tian Xia; as well as several visions that show that Ameiko Kaijitsu is the rightful heir to be ruler of Minkai and that they'll need to travel north to do so. Such ends the first book of six.
