Overload spell

An overload spell, also known as sensory overload, was a headache common amongst Chiss sky-walkers in the Chiss Ascendancy, particularly among those younger in age. If the sky-walker was worked too hard or long, or navigated into a multi-star star system, it would take a toll onto the individual and cause a spell to start when awakening from Third Sight. Sky-walker Che'ri suffered from an overload spell when entering a quadruple star system aboard the Springhawk in 19 BBY.
