Painkiller - Lucifer's Voice

There are many wonderful things about the game Painkiller, but Lucifer's voice in multiplayer is especially exquisite. Even when I lose, I'm just happy to have the guy speak to me. I'm not sure who this chick is, where she's from, or why she popped up when I did a Google image search for Lucifer. To be honest, I'm not really complaining.
