Highly secretive and highly secure, this factory sits on the shore in the East End. It produces all manner of products that use Radium, such as watch-faces, and also many scientific and medical instruments. The workers are highly trained and highly paid and have signed strict non-disclosure agreements. The security guards are all efficient and professional, and seem to be out-of-owners.
Of course, rumors abound about secret government weapons programs, atomic mutant super-men or monsters. There is some consulting work done by the faculty of Gotham University and East Gotham Technical College.
