ADN Device

Geshrinari Shipyards ships have been eqipped with ADN devices for years. The ADN (A carryover from the Alpha/Delta wave Neutralizer) is a form of psionic protection, capable of nullifying all such activity. The ADN has been in use for over 4,500 years, without a great deal of change. Modern ADN devices can selectively allow channels to permit secure telepathic operation and to maintain communication even under psionic attack. The ADN is usually on standby, and activates after sensing an attack or unfamiliar signal.

Activated ADN's are known for causing weird psychological effects on the ship's crew, and older models are notorious for malfunctioning (but are often used anyway).

Newer vessels or refitted ones are equipped with Geshrinari Psionic Signal Controller
