Alcaster and the Star Rock

Hey, aren't you the one that helped me out the other day? Thank you for coming back. Is the 古代之書 safely sealed up? Hmmm... To be honest with you, that's giving me plenty of headaches these days. If you aren't busy or anything... will it be okay for you to help me out here, one more time...?

Thank you so much. After studying and researching for endless hours, I have finally found a clue that can help me seal 古代之書 up for good. The problem is, this book is so powerful, I can't do it on my own. I know it's forbidden to do what I'm about to do, but...to seal it up, I need an item that possesses awesome magical power.

To prevent evil use of this book, we will require a Star Rock. Unfortunately, they are very rare. Only certain exceptionally evil beasts possess them. Please bring me 1 星石 from a monster like Eliza, the Snow Witch, or Nyalmo.

Oh... really? Well I am fully aware of all the troubles you went through to help me out last time. What can I do? Age has caught up with me, and I can't even move around freely anymore. Please reconsider, and if you have changed your mind, then come talk to me.

You did gather up all of those items... not bad at all. You may be much more powerful than I originally thought. Anyway thank you very much for your hard work. And for that, I'll get you a much nicer cape than the one I got you last time. Before all that, though, check and see if you equip. inventory is full or not.

Okay, with this I can seal 古代之書 up right this minute, all thanks to you. I won't ever forget your good deed, and if you ever have some free time in your hand, please come back and visit. I feel like I can trust you to handle anything that may be difficult for others. Take care ...

The only way to seal up the 古代之書 is with 1 星石. I believe you will find it, if you try.

I found out something very interesting. Apparently there's a book with enormous power written mainly on the forbidden magic. That book, however, was lost in the midst of a war and is now almost completely forgotten...but I do believe that book exists, somewhere anywhere...
