The Reign of Winter Adventure Path is on its way, and unseasonable pockets of winter are appearing all over Golarion. It’s surely no coincidence that this is the time when the Queen of Witches, Baba Yaga, is scheduled to return to the frozen land of Irrisen. Will the PCs discover the sinister plot behind these winter pockets and stop them from spreading, or will Golarion be locked in an eternal ice age?
