Dominion

The Tardis travels through a wormhole in space and time that leaves it nearly dead in a Swedish forest in the present day The Doctor reasons one end of the wormhole originates from there—but where does it lead to? The time travelers discover a massive military presence in the area. The wormhole is a result of strange experiments in teleport—but the other end of the time space tunnel is rooted in a bizarre land not even located in our dimension—the Dominion. And the Dominion itself isn't under threat from a shapeless, all-pervading blackness.
