When the Goa'uld destroy the Antarctic Stargate, SG-1 is rerouted to Russia, as the Russians had retrieved the Achilles Stargate from the ocean floor. Teal'c arrives at the facility as well, seeking to use the Stargate to reach the time machine before Qetesh. The two sides agree to a truce and get to Ba'al's time machine: an underground supercomputer connected to hundreds of satellites that monitor solar flares from various stars that could intersect a wormhole created by the Stargate; the flares are necessary for time travel.
Upon the Goa'uld's destruction of the Antarctic Stargate, SG-1 is redirected to Russia, where they encounter the Russians who had retrieved the Achilles Stargate from the ocean floor. Teal'c joins the facility in pursuit of reaching the time machine before Qetesh. The two adversaries temporarily cease hostilities and converge on Ba'al's time machine: a subterranean supercomputer connected to numerous satellites that monitor solar flares from various celestial bodies, which are necessary for traversing through time.
