The Snows of Summer (1 of 6): Every 100 years, the Witch Queen Baba Yaga returns to the nation of Irrisen to place a new daughter on the throne, but this time, something has gone wrong. Far to the south, an unseasonable winter cloaks the forest near the village of Heldren with summer snows. When the heroes venture into the wood in search of a missing noblewoman, they discover a magical portal to the frozen land of Irrisen, whose magical winter will soon engulf all of Golarion unless they can discover the fate of the otherworldly witch Baba Yaga, a quest that will take them through snowbound Irrisen to even stranger lands beyond.
The Shackled Hut (2 of 6): The winter portal has closed, but the heroes now find themselves trapped in the frozen land of Irrisen with an urgent quest—to find Baba Yaga! In order to track down the missing Queen of Witches, the heroes must brave the monster-infested capital city of Whitethrone, where Baba Yaga's Dancing Hut has been captured and put on display. Will possession of the miraculous artifact lead them to the Witch Queen, or will they die a cold death at the hands of Irrisen's White Witches?
Maiden, Mother, Crone (3 of 6): On the trail of Baba Yaga, the heroes find themselves on a new continent, in the barbaric land of Iobaria in far-off Casmaron. The heroes must explore three ancient, mystically linked dungeons in search of more clues to the fate of the Queen of Witches, but they must also contend with savage centaurs and demon-worshiping frost giants who seek to claim Baba Yaga’s secrets for themselves.
The Frozen Stars (4 of 6): Continuing their search for Baba Yaga, the heroes take the Dancing Hut to the planet of Triaxus, seventh world in Golarion’s solar system, now in the middle of its decades-long winter. The heroes soon find themselves embroiled in a conflict between the dragonriders of the Skyfire Mandate and the barbarian armies of a white dragon warlord in their hunt for more clues to the whereabouts of Baba Yaga. Will the PCs ally with one of the warring factions to get the information they need, or will their quest come to an end on a distant, alien world?
Rasputin Must Die! (5 of 6): The search for the Queen of Witches finally ends when the Dancing Hut travels to Baba Yaga’s homeland of Russia on the planet Earth. The year is 1918, and the First World War rages throughout Europe. The heroes find themselves in the wilds of Siberia, where they must face Russian soldiers armed with 20th-century technology to infiltrate an ancient monastery and rescue Baba Yaga from her estranged son, Grigori Rasputin. Can the heroes kill the “Mad Monk,” who has already cheated death once before, and free Baba Yaga, or will they too fall before the horrors of modern war?
The Witch Queen’s Revenge (6 of 6): Baba Yaga has been rescued from the clutches of her son Rasputin, but the Queen of Witches remains trapped inside a magical matryoshka doll. Delving into hidden chambers deep within the Dancing Hut, the heroes must open the nesting dolls imprisoning Baba Yaga, but they also must contend with the hut’s most dedicated guardians, including the former queens of Irrisen. The campaign reaches its climax when the heroes finally face Queen Elvanna, fourteenth daughter of Baba Yaga, inside the Dancing Hut’s innermost sanctum. Will the heroes defeat Elvanna and finally free Baba Yaga, or will their failure plunge Golarion into a new ice age ruled by the Witch Queen of Irrisen?
