National Electric (abbreviated N.E.) was a pre-War company that manufactured holograms.
Before the Great War, Frederick Sinclair wanted to go further in the holographic research, for using the holograms as a means of defense. Big MT, the creator of the hologram technology, refused, imagining the cost to turn the holograms into something beyond walking cameras and greeters.
However, National Electric, based on the technology already established in Big MT, signed off on this project with an exclusive contract with Sinclair to make them like greeters, vendors and security, and fitted them into the Sierra Madre.
