The Ketsurui Fleet Yards in YE 25 transitioned to the Psionic Signal Controller (PSC). The PSC is a form of psionic and telepathic protection, capable of nullifying all such activity. The device can selectively allow channels to permit secure telepathic operation and to maintain communication even under psionic attack. The PSC devices also negate 'magical' attacks and effects. This PSC is safe enough to remain active at all times, unlike older “ADN” devices. The field generated by the PSC protects the entire ship, and extends only one meter out past the hull (thus, it will not create an obvious psionic “dead zone”).
