Daily Monster 144: Valravn
Region of origin: Denmark
Valravne were depicted as the result of ravens who ate from the bodies of kings or generals who had died in battle but had not yet been given proper burial. The birds would gain intelligence and supernatural powers from consuming the leaders, such as taking on the forms of knights or wolf-raven hybrids,
Alternatively, in some darker tales the creature would have once been a man in life, now a restless spirit taking the form of a raven, with the only way to break the curse being to eat the heart of a child.
