A crystal clear lake, Lake Ophir is the origin of Eridu City. People gathered around its pure waters and refused to despoil it with brick and mortar. The lake is as holy as the shrine, but despite that, there was never particularly noteworthy about it--not until now. Now, the lake is now dark and brackish, not fit for drinking--even touching it isn't advisable. An unsettling whirlpool has opened up in the center of the lake. Where it leads, no one knows.
