Kiley telescopes detected the warp signs of Federation, Klingon, and Kelpien starships engaged in the battle near Xahea in 2258. The Kiley used this telemetry to reverse-engineer matter-antimatter reactors. By the following year, the Eldredth faction had constructed a warp bomb, with which they hoped to quell the revolutionary faction Palion once and for all. Rumors about the weapon spread by the Palion incited mass protests and civil unrest against the government. By the following year, the violence between them threatened to escalate into a global civil war.

The Federation detected the signature of the bomb and, mistaking it for the development of warp drive, dispatched USS Archer to investigate and potentially initiate first contact. The starship was detected by an Eldredth military installation as an unidentified flying object. The Archer's crew, were captured after they beamed to the surface.

USS Enterprise subsequently arrived at Kiley 279 and came under attack. The crew were forced to disguise themselves as Kiley and infiltrated the secured underground facility where the Archer's crew were being held. After learning how the Kiley developed the warp bomb, Enterprises captain revealed himself and his crew to the Eldredth leader and compelled her to meet with her Palion counterpart. The CO described the devastation that Earth had suffered during World War III to the Kiley people, and offered them the chance to avoid that eventuality and join the Federation. Opting for peace, the now-united Kiley began learning about the interstellar community and researching space travel[3].




The Kiley are externally characterized by thickened eyebrow ridges with dark striped markings; their arms and legs have similar patterns. Their eyes tend to be light blue-green irises.





Tagball was a popular Kiley sport, which included professional teams such as the Cone Rockets and the Boom Shield.
