Mineral of the legend

Hm… According to what is written here, the mineral of the legend is in the Ghost Valley. I have to go there, but I'm a little worried because it's such a dangerous place. Can you help me a little? Please hunt 25 Thunder Griffins from the Ghost Valley. That will create enough of a distraction so the monsters do not attack me while I'm looking for the mineral of the legend. I entrust you with this task. May the hands of the spirit be with you on your journey.

Please hurry and hunt 25 Thunder Griffins from the Ghost Valley. Only when you start hunting can I have the peace of mind to look around the vicinity. May the hands of the spirit be with you on your journey.

Hm… Because of you, I was able to investigate safely, but… it seems that I have misinterpreted the information on the stone tablet. I could not even find a trace of the mineral of the legend. So it's not there. I must continue looking elsewhere. Anyway, I won't forget your helping me this time. May the hands of the spirit be with you on your journey.
