Elder Cronos:
Because I made a promise to Mimyu.
One must keep their promises to fairies. Have you not heard stories about what happens to those who don't?
Well, if you haven't lived for as long as I, it's no wonder you don't know. Anyway, I would like to ask you to go help Fairy Mimyu. What do you say?
I'll make sure to reward you well for helping Mimyu. Well, not me, but Mimyu will.
"I will help."
