So the lesson here is that TSR and/or Wotco like to give existing things a silly hyphenated name and then copyright them.
I hereby copyright the name "Qwax-Nagvor" for the holy one-horned magic horses of my campaign world, which are an original creation loosely inspired by the mythical unicorn. A forthcoming supplement will detail their anatomy and ecology as well as providing Qwax-Nagvor-centric adventure hooks.
