The Sunspire Difference of Claw and Fang

If a Knight wanted to change purpose? It was a confusing question. A knight who decides to change his purpose isn't a real knight or quits being a Knight. Nishu didn't think it was possible to quit, It takes so much to get this far. Why would anyone even think about changing purpose?

He tilted his head as he looked at her. "Changing purpose? Then a Knight wouldn't be a knight anymore. I wouldn't understand why a Knight would ever change his purpose. Knights are suppose to be known as valueable wolves for any situation. Why not be a Knight if you can, right?" He said, believing Knights to actually have the best purpose in life.
