Rumors about the Relic

If you go to the Ten Year Desert, there's a place called Village of the Shadows. Humans established it long ago in times of conflict. On the outside, it looks like a place where bandits live, but in fact it's an outpost to observe the Orcs. When Ugdrasil raised his army, he of course didn't leave the place intact. The legend goes that after half a day of battle, all Humans guarding the village died, but the Leader Lan Sand displayed bravery until the very end. So Ugdrasil highly praised his valor and buried Lan Sand's Sword under the earth of Village of the Shadows to protect the land even after his death. Recently, a descendant of Lan Sand asked me to find the sword. I don't like to get involved in this kind of work, but I think the descendant's request is justifiable. So I said yes, but I'm not used to such work. Grave Robber Toray, north of this village, knows much about the relics near the village. Give him a Gorgon Potion and get information.

This may be a difficult task, but please help me. Give one Gorgon Potion to Grave Robber Toray north of the village and get information.

This is the Gorgon Potion! I was thinking I wanted one of these. You must need something from me. What is it?
