Role

The area exists to support simulation testing for the Evangelion program. It is thrust into crisis in Episode 13, when the Angel Ireul enters headquarters through a contaminated panel, the 87th protein wall, newly fitted in the Pribnow Box. The infection sweeps through the whole zone and claims the simulation bodies, and once the area is evacuated the Angel exploits the captured systems to connect with the Magi supercomputers and hack them.
