What Lay Beyond: Gateways, Book Seven2001

Created by the incalculably ancient Iconians, whose transcendent technology is quantum levels beyond that of the Federation and its allies, the Gateways offer instantaneous transport across unimaginable distances. Throughout the known galaxy, from Deep Space Nine to the New Frontier, from the Delta Quadrant to the bridge of the Starship Enterprise, the sudden reactivation of the Gateways has destabilized interstellar relations between planets and cultures previously separated by countless light-years.
