Chiriko tells you, "It is an honor to greet you. I have a proposition for you, if you are interested. There are some recent additions to the Isle known as the Dark Isle, specifically the Black Coral Golems. If you would be willing to go there and prove your prowess by destroying 100 of these strange golems, I will reward you handsomely for your actions."
