The Elementals' Réponse

The Sand Family's Sword is truly a fine sword. I've been looking at it while I waited for you. As a merchant, I've handled a lot of weapons, and I can get to know them quite quickly. I'm sure it's proper for the descendants of the Sand Family to want the sword, but I don't think it belongs to anyone anymore. It's been a servant of petty wars for so long, it deserves a respectable rest, so I decided to commit this Sword to the Elementals, giving up the great fortune I could have made by selling it. I need you to help me. If you go South East of the Village you can find one peculiar-looking rock sticking out there. You can commit the Sword to the Elementals through that rock. Please do as I ask!

Offer the Sand Family's Sword on the rock at Giants Highroad. There must be a reply from the Elementals.

I put the Sword on the rock and took a step back. The sword started to glow, then it disappeared. The only thing left was some faint music. I think that was the reply from the Elementals. Looks like the Sand Family's Sword will no longer have to remain in the times of chaos.
