Queen Jadwiga was a daughter of the Witch Queen Baba Yaga and the first ruler of the land of Irrisen. She took the throne during the Winter War in 3313 AR, after conquering the Linnorm Kingdom of Raemerrund in far northwestern Avistan. During her 100 year-long reign, Queen Jadwiga established most of the country of Irrisen as it still exists today, 1,400 years later. Queen Jadwiga was removed from office, along with the first generation of her children, by Baba Yaga in 3413 AR. She did not die, but was taken from Golarion to supposedly travel with her mother to parts unknown, and was replaced by her sister Morgannan.
Descendants of Baba Yaga are known as Jadwiga, after the first queen.
