L is for Lamia

Lamia went mad with grief, and took her revenge by devouring the children of others. Some versions of the tale suggest that Lamia was turned into a monster because of this, with a serpents tale below the waist.
Lamia eventually became the Lamiae, monsters similar to vampires; beautiful women who seduced men and then drank their blood.
