Empusas are the handmaidens and elite agents of Calistria. In their true forms, they possess red antennae, gossamer wings, and a wasp's legs, but can also take the form of elves to infiltrate society and manipulate events to achieve their missions of vengeance. They stand six feet tall, weigh 120 pounds, and can manifest a lash that only exists as long as they carry it.
