The Liderc may appeal to the sexual interests of readers. This vampire-like being share a similar quality with the Succubus or Incubus. They tend to "love someone to death" with sexual activities.
According to Hungarian folklore, there are three varieties of Liderc. The first and more traditional form is that of the csodacsirke. One hatches from the first egg of a black hen kept warm under the arm of a human (there are variations of this). It can take form of a chicken or human but always has one goose foot. The Lidérc attaches themselves to people and becomes their lover. If the owner happens to be a woman, they will morph into a man. However, it doesn't have the desire to pleasure the woman. Instead, it fondles her, sits on her body and sucks her blood, making her sick and weak. It also carries out tasks to find treasure. This generous gesture would soon become annoying as it demands more work constantly. There are two ways to rid yourself of this Liderc. You can give it an impossible task such as hauling sand with a rope, or lock it into a hollow tree.
The second form known as földi ördög shares some qualities with the first one. It can be hatched from a black hen's egg, but it's mostly found in glass bottles, rags, and pockets of old clothing. They can also make their owners rich but they supposedly give their souls to the Liderc or possibly the Devil. Doesn't seem worth it.
The third and final variety is a Satanic Lover called ördögszerető (though they have many names throughout different regions). They appear as a fiery light or a bird of fire flying in the night sky and sprinkling flames. It can take the shape of a human, usually of a dead relative or lover, and leaves footprints of a horse. They enter chimneys or keyholes, bringing sickness to their victims. The only way to bar them from your home is to burn incense and birch branches.
