Valkyrie Circle -- that's so cool!
Well, one of my cats is named Valkyrie, so I just stole it from her.
I didn't know what a valkyrie was, so I looked it up -- it's from Norse mythology -- valkyries are winged creatues that lead dead battle heros to Valhalla -- but I really just thought it was a cute name. And my cat leads nothing to anything, although she is the boss of the other cats.
