Daisei Chirana tells you, "Come here. I would have a task for you to complete."
Daisei Chirana tells you, "There is, upon the Dark Isle, a new kind of coral that has begun to appear - a black coral, radiating the power of the now-departed Grael."
Daisei Chirana tells you, "We must determine what to do with this power - if it is safe to utilize, or if it must be destroyed."
Daisei Chirana tells you, "Bring exactly ten of this black coral to me. Any more and you risk damaging yourself."
