Wolf Witch (Cassandra Gava) is a villainess from the 1982 movie Conan The Barbarian.
Conan on his travels meets a strange lady whom lives in a cottage in the middle of nowhere. She invites the Barbarian in to warm himself by her fire.
This is the Wolf Witch. When she first meets Conan she appears to be beautiful and rugged with long black hair and wearing tight fitting skins and a boars tooth necklace.
It's hard to tell her true intentions as she at first gives Conan food and wine. She calls him a slave and a barbarian and taunts him. She then begins to talk about the myth that a great one will one day come from the north. She begins to crawl around making animal noises.
Conan takes her in his arms and in front of a roaring fire they begin to make love. The passion changes the woman and she begins to change. Her eyes turn while like those of a wolf and her teeth turn sharp and she begins to try and bite Conan. She is dangerous. He realizes that it was a trap and he was lured into the cottage to be seduced and eaten.
The flames roar and her mortal body is burned away releasing her fiery spirit. Which crashes about the cottage and then out into the night. Conan is left alone, unsure as to what just happened.
