World of Adventure 2.0
The morning after then the great earthquake struck the region, the Silver Sea had become clouded with a greenish tint. While the waves still sparkled the same as they had before, the name was quickly coined and soon after stuck.
No one knows what caused the greenish tint to arise in the waters; many believe that as bad as the earthquake was above the water, below the surface must have suffered a far greater disruption. Many assumed the tint would fade as sediment settled back down to the sea floor, but it has been nearly twenty years, and there has been no change.
The dwarves believe that a vein of valuable minerals has opened up on the sea floor, and are trying to find a way to either prove it or explore the sea floor to uncover the truth.
