Children of Judas

The Children of Judas are from Serbian, Bulgarian, and Romanian myth. They are a type of vampire who always have red hair and can drain victims of every drop of blood through a single bite. Their bite marks often resemble the way the Latin number thirty is written, XXX, symbolizing the amount of silver Judas took to betray Jesus.
