The soldiers brought it here. They told me that they got the jewels during the fight with Turek Orcs. The northwest coast of Gludio is a place where the relics of Elmoraden empire are often found...
It is also written here in the account book! Three jewels of empirical style, purchased by Leopold of the Black Lion Troop. Ask him in person about the details. I think he lives near the rebuilding site of Gludin.
