Optic's X-Ray vision and tech knowledge keep picking up useful information. One outbuilding contains some sort of supercomputer, control terminal, and backup generator, and has a rotating tower on top he recognizes as a sensor array of some sort. It seems the sensor array is separate from communications, which seems to include a row of three satellite dishes and a building like the sensor building with a few antennas and its own computer systems and backup power. Another outbuilding facing the road conceals a row of railguns. There is a similar building near the cliff edge, which additionally has some computerized firing controls and backup power. Instead of the side walls opening up, it looks like the roof and top half of the walls do. It seems to be an air defense system of some sort.

You are led into the house, and greeted by a butler. It is full of fancy furnature and paintings. He takes you inside, where the entryway faces a stairway that rises and splits into two different directions. There are two sets of double doors on the ground floor, one per side, as well as two more doors on each side of the split staircase leading underneath it.
The butler and Mr. Von Krup lead you to through one of the sets of double doors, where there is a sitting room of some sort. A giant painting on the wall turns into a computer screen. There are two men and a woman in lab coats standing around, as well as a fancy-looking man in a suit with long, slicked-back, blond hair and very sharp features. The man introduces himself, saying "I am Gunnar Jonasson, the leader of this facility. You have these engineers at your disposal to finalize your specifications."
