Several armed guards are posted near entrances. Northeast from the main entrance leads to Resistance leader Evfra de Tershaav's office. Southeast leads downstairs to the Infirmary and an underground training facility. Overseen by a hardnosed Resistance Captain, the training facility is where Resistance members test their combat mettle against themselves or holographic enemies. Quartermaster Istaal sells items from this place, and Cora Harper often loiters here to observe the drills.
Lining the hallways of the headquarters are numerous terminals, often with an angara working on them. Evfra's own chambers has a gigantic viewscreen and staffed with more operations personnel. It is built in such a way that the northern Aya landscape as well as the training facility can be viewed from here.
Outside the headquarters proper, the nearby Holographic Message Terminal and fast travel station aren't technically counted as part of the headquarters, but they are for some purposes.
