In most Macedonian tales and folk songs they are described as extremely intelligent, having hypnotizing eyes. However, sometimes Zmey's could be men who would astrally project into the sky when there is a storm to battle the Lamia, a female evil version that wants to destroy the wheat. They were also known as guardians of the territory, and would even protect the people in it. Hostile behaviour was shown if another zmey comes into his territory. They could change their appearance in the form of a smoke, strong spark, fire bird, snake, cloud but almost afterwards he would gain the form of a handsome man and enter the chambers of a young maiden. They fell in love with women who were conceived on the same night as them, or born in the same day as them. He usually guards the girl from a small age and his love lasts forever. Some girls get sick by loving a zmey, and symptoms include paleness, shyness, antisocial behaviour, watery eyes, quietness and hallucinations. They didn't live a long life, because it resulted in suicide. Zmeys would kidnap girls and lead them into their mountain caves where she would serve him.
