It's called a Nightmare because it's named for the DnD monster. Also, there is nothing Knightly about it. We named it what we did because we wanted to, and because a mare is a female horse, it's the colour of the night (black sky, white moon and stars) and it's something from a nightmare. Knightmare gives no real addition to the name that makes sense to me.
