I am Katja, the Nightmare Rider. I work for Dark Core, an organization that intends to unleash the tentacled monster Garnok to take over the world. Everything I touch dies, and turns cold and gray. I can also create ice or induce cold weather. I try to be numb to all emotion, but occassionally there's cracks in my shell. My horse Mortifa is blind, controlled by a collar around her neck, and conditioned by the haunting notes of my violin to remain on high alert.
