Maybe it's Grendel!

I don't know if you are aware of this, but the chief of Ellinia, Grendel the Really Old, used to lay his hands on a dangerous form of magic. These days, he steers clear from the past and moved on to become a wiseman, but since he does have a past, his name is always mentioned on the list.

I received a word that the Puppeteer may be connected to him. It is true that his forte used to be putting curses on the dolls, so it's not totally out of question, so I'd appreciate it if you can find out some more information on Grendel the Really Old.

I will bring Grendel the Really Old out by telling him that I need to talk to him about something. While I hold on to Grendel the Really Old, your job is to enter Grendel the Really Old's Magic Library and search through every part of his library. This is just in case we find an item that may put all of us in grave danger.

Appearance-wise, Grendel the Really Old has the look of a warm-hearted old wizard, but... appearance is definitely not everything. We can only prevent the rebirth of Black Mage by questioning everything we see.

...a black shadowy figure came out and attacked you? How can this take place at Grendel the Really Old's house? This sounds like one big conspiracy here...

I'll have to sort this all out in my mind. Talk to me in a bit.
