Hypernavigation Fatigue

Condition where Interstellar Navigators become fatigued to the point of not being able to utilize their psionic abilities. They are also physically exhausted. Typically it only affects their clairvoyant functions, but sometimes Burnout occurs, affecting all psionic ability and/or further impacting their physical bodies.
Sometimes called Hype, it has slid into the common vernacular as a condition where a person, often unexplainably, is stunned, disoriented or rendered unconscious.
