First Appearance: Wars Are Won By Those Who Dare: Laissez Bon Temps Rouler
Daphné Lager is the current alias for the vampire Delphine LaLaurie. She hates Bayonet Bellmonte in part of her own prejudices and in part that Jacques Bougeois killed her childe-lover for biting the Martian mouse when she was a child. He didn't drain her after discovering human Vampires dislike Martian mouse blood.
She's the one who sends the distress call to Mars once she learns of Gruyere's current plan in hopes that "la pute de la souris" (the mouse whore) will go back to Mars. She hypnotizes Charley with a message to Bayonet when infiltrating Gruyere's base of operations doesn't work. She justifies her animosity by saying "l'enfant d'esclaves est un esclave" (the child of slaves is a slave).
