That's what most magicians are. At least from my knowledge previously. It is not a problem. I have taught plenty of people with little knowledge. Harry once learned from me when he didn't know even very many spells.
It is the name of the star muleonis. In the Leo constellation. Most know me as Regulus instead since the majority of people from my world are the opposite gender from what I'm aware of. At least the ones I know. Also a star in Leo, but Alpha Leonis. Heart of the lion. Ah. That sounds definitely unfortunate. Well, hopefully you can avoid it again.
