Suspiria's array was a large space station in the Delta Quadrant. Built by the Nacene and powered by a tetryon reactor, the array served as a location from which Suspiria could protect and serve the Ocampa on board.
In 2372, USS Voyager found Suspiria's array, after being pulled into the Delta Quadrant by her mate with a similar array. Aboard the array lived several hundred Ocampa. The residents of the array, with the help of Suspiria, had developed heightened mental powers and extended their lifespans. The Ocampan leader, Tanis, helped Kes develop her powers while leading Voyager into a trap so that it could be destroyed as revenge for what Suspiria believed to be their role in the Caretaker's death.
