A balaur (pl. balauri) in Romanian folklore is a type of many-headed dragon or monstrous serpent, sometimes said to be equipped with wings. The number of heads is usually around three, but they can also have seven heads or even twelve heads according to some legends.
The balaur in folktale is typically evil, demanding or abducting young maidens or the princess, and defeated by the hero such as Saint George or the fair youth Făt-Frumos.
There is some lore in which the balaur is considered weather-making, and living in an airborne state, but these types of balaur are sometimes interchangeably called hala or ala, being confounded with the pan-Slavic air and water demon. The balaur (instead of the zmeu) is the vehicle of the weather-controlling Solomonari according to some sources.
There are also legends about the balaur in which they can produce precious stones from their saliva. Also, it is said that whoever manages to slay it will be forgiven a sin.
