In ancient Greece there was a vampiric being known as Lamia. Her name was used in early versions of the Bible to mean “screech owl” and “sea monster”. She was a monstrous creature that fed exclusively on the flesh and blood of children each night. There are a number of vampiric beings, creatures, REVENANTS, and the like throughout ancient times that share the name Lamia, which translates as “dangerous lone-shark”.
