The first part of the two-part Stargate: Horizon season finale has been released! Things kick off with “Preemptive Strike,” which will see the return of several well-known recurring characters as the second season of the fan-written, virtual series comes to a conclusion.

As Horizon celebrates David Connor’s promotion to Major, the celebrations are cut short when an old friend arrives with troubling news. Sivok, who has spent the past several months searching the galaxy for more Draque to join his cause, informs Grant that the Enoly are about to carry out their biggest strike yet. Quickly a plan is set into motion to prevent the Enoly from carrying out their attack.

Meanwhile, the Vorians are facing their own problems. Tensions with the Kih’Andari rise, and civil war seems all but inevitable. Callen approaches President Adari with an idea for how to solve the situation in a peaceful way.

Guest characters include Sivok, Lonik, Loral, and President Adari, as well as a character who will be making a surprise return. “Preemptive Strike” was written by executive producer Alex Rubit, and will lead right into next week’s second half of the finale, titled “Revolution.”
