The Moroii is a living vampire in Romanian folklore. Some stories refer to the creature as a vampire ghost. The vampire can be male or female.
The female Moroi is called a moroaica.
Some stories associated the creature with strigoi or werewolves.
In modern myths, the creature is said to be the live-born offspring of two strigoi or an infant who died before being baptized.
Some stories say the moroi is merely the ghost of a dead person that leaves the grave to draw energy from the living.
