You are in the Computer Center, a dimly-lit, low-ceilinged cave that stretches into the distance beyond the limit of your vision. The vast space is filled with countless rows of computing equipment housed in blasi blue paneled frames.

The high-pitched keen of electronics and the low-pitched hum of air conditioning constantly fills the cave.

The climate-controlled air smells faintly of ozone and Brylcreem.
