Quinn Mallory, while working on an anti-gravity machine, accidentally creates a portal to a parallel universe. Eventually, his friends and an unwilling participant accidentally get stuck traveling among parallel worlds, trying to survive, and learning that sliding can lead to fatal results.
The stable wormhole discovered by the Deep Space Nine crew is known to the Bajoran people as the Celestial Temple of their Prophets. Sisko, as discoverer of the wormhole and its inhabitants, is therefore the Emissary of Bajoran prophesy.
