The Plumbiers, later known as the original Earth Plumbers, were a society who fought against the supernatural before first contact with alien life predating the intergalactic Plumbers on Earth.
The Plumbiers were known as the original Earth Plumbers before they disbanded as Earth joined with the intergalactic authorities. Their original organization had been shut down and all their operations had been taken over.
Through they fight the supernatural, Plumbier technology can fight on par against alien technology despite first alien contact only occurring in the 18th century.
