DERVISH camouflage system

The DERVISH camouflage system is a pre-War technology used in Hidden Valley.

Background
Mentioned in the bunker's datastore terminal, the DERVISH camouflaging system is a cloaking mechanism, serving to protect the self-sustaining shelter. It was part of the Hidden Valley project's overall goal of creating a location for high-ranking VIPs, serving as a safehouse to preserve their command structure in times of crisis.

Gameplay
The bunker itself is located several hundred feet below the surface, utilizing the system's visual and electronic interference to prevent such airborne or long-range enemy weapons from targeting the facility. The normal soil around Hidden Valley has been supplemented with a combination of aluminum and various silicates, dispersed using a widespread network of industrial fans to blanket the area in a cloud of chaff.

In the event that the location was threatened, the bunker's DERVISH camouflage system would make targeting the site impossible for automated systems, forcing aggressors to rely on guesswork. Combined with the electronic countermeasures of the nearby array at Black Mountain, the bunker at Hidden Valley would be impossible to target.

The system was only intended to be used in case of emergencies. However, the Brotherhood of Steel's extended occupation of the facility has put stress on the systems over the last few years, which were not designed to accommodate such long-term usage. The group relies on the defensive system to mask its patrols leaving and entering the area at night. Elder McNamara explains that the air filtration system is unable to process the quantity of particulate it has been forced to cope with. As a result, the air quality has started to decline slowly, leaving only a few months left before it shuts down completely, rendering the air in the bunker impossible to breathe.
