Origin
A fashion designer, Katie designed clothing for performers, and was successful for some time until she began experiencing artist’s block. To reinvigorate her talents, she performed a ritual that enabled her to snare and skin demons to create leather garments. When her payment for the ritual came due she fled, allowing dozens of innocents to die as the demons hunted her. Ultimately she was given a guitar pick that once belonged to John Constantine, and which protected her for as long as she wore it.
