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!

A deadly storm shipwrecks the passengers and crew of the Jenivere upon infamous Smuggler’s Shiv, an island off the coast of the jungle realm of Sargava. If they’re to have any hope of escaping the notorious pirates’ graveyard, the survivors will need to band together to outwit the isle’s strange beasts and legendary menaces. But can the PCs unite the swift-to-squabble castaways, especially when several seem to have mysterious goals of their own? And does Smuggler’s Shiv hide secrets even deadlier than its desperate denizens? This is part one of the Pathfinder Adventure Path "Serpent's Skull", but can be played as a standalone adventure that lasts approximately 10 four-five hour sessions. Great for first time dungeon masters. This is not a seafaring adventure. The PCs are shipwrecked on an island for the entire duration. This adventure ends with (hopefully) the PCs finding a way off the island (reaching level 3). It is therefore a great starting adventure with a definitive conclusion. After this module, you can continue with part two or change into your own homebrew.

The Pathfinders descend deeper into the ruins of Bonekeep, a centuries-old siege fortress. The deeper dungeons hold even deadlier threats, yet even they cannot compare to the terrible revelations of the tower's true purpose.

Will you make it through sewers, swarms, and sanctuaries to uncover the truth or will the dangers of the Augustana underworld consume you forever?

When four statues of unspeakable power were found in a tomb in Osirion and then stolen, the Pathfinder Society assumed they were gone forever.

Finding the smuggler dead and a familiar face from Absalom responsible, your task quickly becomes a race to retrieve the statues before their brutal power can be unleashed on the citizens of the Satrap. Can you find the statues in time or will Sedeq be swallowed in a plague like none Golarion has ever seen?

Famed Pathfinder Bodriggan Wuthers disappeared from his dig site beneath the House of the Immortal Son in Taldor's gilded capital of Oppara.

Sent to locate Wuthers, the Pathfinders must attend an opera with members of the Oppara elite in order to gain access to the secretive theater's dig site. When a cult crashes the performance and the nobility change into hideous walking dead, the Pathfinders are forced to choose between finding Wuthers or saving themselves.

The strange city of Carrion Hill has long loomed over the surrounding swamps in eastern Ustalav, yet its rulers have shifted many times through the centuries.

A monster stalks the twisted alleys of the city, spreading panic before it and leaving destruction in its wake. Can the Carrion Hill Horror be stopped?

When a Pathfinder Society Priest of Nethys disappears in northern Geb while studying the Mana Wastes, the Society sends you to uncover her whereabouts and find her journals.

Will you solve the mystery of Bitter End or find yourself lost forever in the Mana Wastes?

The slave markets of Katapesh may be an unsavory sort of business, but the trade metropolis’s enigmatic law enforcers have few qualms with the legal act of selling and buying flesh. Other factions, including the abolitionist Eagle Knights of Andoran, have their own opinions on the matter, however, and frequently send undercover agents into dangerous territory to break up slave rings. When one such Eagle Knight goes missing while investigating an underground slave operation beneath the dilapidated Twilight Gate district, it’s up to the PCs to delve an abandoned (but hardly uninhabited) qanat beneath Katapesh and discover her dire fate. Yet not everything is as it seems in the dank slave caverns under Twilight Gate, and clues hint that the slavers may have even more loathsome connections than initially suspected.
