Keshians represented a sentient species that closely resembled humans in almost every way. Their eyes were the sole discernible difference; they were unusually large and possessed an unusual color, granting them the ability to perceive a wide spectrum from ultraviolet through to infrared. This characteristic was exploited in aerial combat by the Keshian Iolo Arana, who served as a pilot for the New Republic to his benefit.
The initial depiction of Keshians occurred within Before the Awakening, a young adult novel authored by Greg Rucka and released in 2015.
