What's a good name for a brotherhood of chosen sorcerers?

I'm writing a story about a brotherhood of witches chosen to battle evil, something similar to the Charmed Ones, but I'm having a hard time brainstorming what to call them. Too bad the Charmed Ones is already taken. I want something similar, to that of the Charmed Ones, but something that strikes fear and a name that is bold, strong, and masculine.
