Varcolac (Romanian)
A varcolac (or varcolac or vircolac) in Romanian folklore may refer to several different figures. In some versions, a vârcolac is a wolf demon. As the Norse Fenris, a varcolac may swallow the moon and the sun; it's thus responsible for eclipses. In Romanian, varcolac commonly means "werewolf". It can occasionally mean "goblin".
The word varcolac is a loan from Slavic, meaning "werewolf" (etymologically "Wolf's Fur"). The pricolici is another form of varcolac, also resembling a werewolf. Some legends say it is a ghost or vampire while others say it is a werewolf. There are many different explanations given for a varcolac's origin.
