Lake of Ill Omen

The Lake of Ill Omen is a location in the Dark World in The Legend of Zelda: A Link to the Past.

Situated where the way to Zora's River was in Hyrule, the Lake of Ill Omen has only one particular feature - a circle of stones. If Link throws a Bomb or a Skull into the middle of the circle, a fish will appear and gives him the Quake Medallion in exchange for not doing it again.
