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!

There, the PCs face powerful new threats unlike anything they’ve seen before, and learn that the dangers facing their kingdom are even greater than they feared, for the fey ruler of Thousandbreaths is about to absorb the Stolen Lands into a bauble for her own purposes, an act that would scour clean the region and leave behind nothing but a wasteland.If the PCs hope to save their new kingdom from this threat, they must combat the nymph queen Nyrissa both by stopping the various blooms in their kingdom and by traveling into Thousandbreaths itself to confront the dangerously insane nymph.
