Mylingar are mischievous children spirits that like to play pranks on people. They could transform into animals that humans capture but then transform back into a child and run away laughing.
They have to try to convince someone to bury them in hallow grounds. The Myling will jump on the back of the person and hope for help. This person will carry the Myling to a cemetery, but sometimes it's difficult for the benefactor to do so. The Myling sometimes gets heavier and heavier even causing their benefactor to sink into the ground or suck the life from the benefactor making them weak. If the person is not able to bury them they kill that person in rage.
