The holy grail of lost tech! It is located somewhere in west virgina along the appalacin mts. when the bombs started dropping, the forts automated defenses when on full lockdown. the only way to reach the fort is a 2.5 km cave system that meets with a back doow. its front entrance was lost a century ago in a rock slide. the V.I. in charge of the fort keeps it in good repare with scores of drones. in addition, a geothermal electricity should keep it powered for centurys. It is rumors that this was a Glitterboy manufacture/storage facility. The Brotherhood of Steel has never been able to locate the facility, let alone breach it and find out.
