Great illustration of this Slavic legend. Thinking about Slavic gods and legends and myths, they are not so pretty and dreamy :) Like there is always something threatening and scarring those who believe.
As children we were frightened with baba Jaga https://en.wikipedia.org/wiki/Baba_Yaga
Even my great grandmother forbidden us kids to imitate owl howls because it was believed it brings death to home :(
