Sardicktown
From Tardis Wiki, the free Doctor Who reference
Sardicktown was a town on a human colony planet near to the Horsehead Nebula and was ruled over by the Sardick family in the 44th century. At night, fog was prevalent throughout the town. This fog had unusual properties that allowed certain species of fish to swim through it. Since this included a shark-like species, Elliot Sardick created a machine that could control the clouds and fog to keep the fish away when people were on the streets. There were small pools of permanent fog used by the Sardicks to keep people cryogenically frozen.
There was a day when the cloud bank fell and fish attacked a school. Nobody was seriously harmed. (DW: A Christmas Carol)
