Elder Cronos:
Are you kidding? You made a Fairy Stone? Seriously? I didn't expect it to work! May I see it? Oh my, it is splendid! Consider how lucky you are, my young friend. A wizened old sage like myself never expected to see one with my own eyes. I wonder what you should do next?
Oh yes, I know! You have met Byron, the guard of this village... He is from here, and seems to know more than anyone about the creatures in this place. He will tell you what to do next.
