Lake of Ill Omen

Northeast of the Potion Shop in the Dark World, there is a ring of stones where a Zora resides. Near the ring, there is a sign that says, "Curses to anyone who throws something into my circle of stones." If you ignore the sign and throw something into the ring of stones, the Zora appears and says, "Was it you who disturbed my peaceful nap? I will give this to you if you go away!" The Zora then gives you the Quake Medallion. Throwing another item into the ring of stones, causes the Zora to spit a fireball at you.
