Kunyans

The Ferrine histories speak of Kunyans, Iazun warriors who developed a bond so strong with their polar beats they merged with them, becoming a single being with two heads and eight appendages. However, the government of Anuaran claims Kunyans never existed, as Iazuns never serve as warriors.
There is, however, an Anuaranian legend collected in the book Tales From The Far North which claims that the war between the Huawents and the Selkies also involved "creatures like polar bears with two heads and arms" who fought on the side of the Huawents.
This is similar to art found in am abandoned castle on Narwal Island.

Perhaps all of these legends stem from a single tale wich has been lost to the waves of time. We may never know.
