The lines started appearing when Race was seventeen. One moment in class, he was working through a few physics problems, completely focused, and the next, he was staring at the black line on his arm. It was thin and scratchy like a ballpoint pen, and didn’t seem to follow any discernable pattern. Race watched in shock at the line continued slowly across the top of his forearm before coming to a close back at the start. He stared at the shape, trying to find any meaning in it, before realizing that it looked a little bit like a dog. After uncapping his pen, Race drew a quick face on what may or may not have been a dog, along with a bone.
