the work of a master craftsman

Exploration Stage: Borderland
From: Vera
Description: Is the ghost lyre affecting the fog? Of course, I'll gladly research the lyre! But I was in such a hurry to get here that I dropped my research tools somewhere. Could you please find it?
Completed: It is my tool! Yes, according to the measurements, this lyre is made of an unknown alloy. I see the letter "M." It seems that the masters of the Five Wise Guardians were involved in the making of this instrument.
