This vampire spirit originates from India. Usually he’s invisible, but when he’s hunting, he takes the corpse candle ball of light shape. He lures travelers into the forest with the light and making strange noises.
If they don’t come to investigate the noises, he sends his hunting dogs to chase them into the forest. Until they are so far in, there’s no chance of help then he attacks. He drains the body and leaves the corpse for his hounds to eat.
