Some legends say it's a ghost tor vampire (Strigoi) while others say it's a werewolf, but unlike a shapeshifter, a Varcolac is born from the spirit leaving the mouth during sleep. Varcolaci are said to fasten themselves to the thread of people spinning at night, then going up to eat the moon and cover it with blood.
These creatures are said to be created by:
- souls of unbaptized children
- children of unmarried parents, cursed by God
- they rise upon sweeping dust out of the house at sunset, in the direction of the sun
