Jens' Reign of Winter
The queen of witches
Baba Yaga appears as an ancient human crone, often seen carrying her witch’s broom and a large basked filled with sundry items on her back.
The queen of witches, Baba Yaga invaded Golarion from another world in 3313 AR, making war on the Lands of the Linnorm Kings. Within 23 days the Winter War was over and she established her realm Irrisen.
Now she returns to Golarion every 100 years to place a new daughter on the throne
