About a hundred or so years before you were born, a Dark-Hunter made the mistake of falling in love with his Talpina. Unfortunately for the rest of us, she didn't pass Artemis's test. Artemis was so angry, she stepped in and banished the Talpinas from us, and implemented the oh so wonderful you're-only-supposed-to-sleep-with-them-once rule. As further backlash, Acheron came up with the never-touch-your-Squire law. I tell you, you haven't lived until you've tried to find a decent one-night stand in seventh-century Britain. (Talon)
