This is my new IATTAR racer, Slug Lights. It's story:
Colonel Harding and a few close friends, fans of IATTAR racing, wanted to compete but were put off by how dangerous the tracks were, and the sheer amount of vehicles driving simultaneously. They started their own league, which took place underwater, called IATTAUR, or Interplanetary Association of Tracked & Thrust Assisted Underwater Racing. They were sued soon after by the original racing association for patent infringement, and were forced to shut down. Colonel Harding kept his prized racer called "Slug Lights", though, which is why you see it here today.
