In the last days of the twenty-fourth century, caught in the crossfire of the apocalyptic confrontation between the Bajoran Prophets and the Pah-wraiths, Captain Benjamin Sisko and his crew face what might be the final millennium. On one side, the Pah-wraiths' new Emissary -- Kai Weyoun -- promises his followers that when Bajor's two Celestial Temples are restored as one, all beings in the universe will ascend to a new and glorious existence with the True Prophets. On the other side, the scientists of Starfleet predict that when the two Bajoran wormholes merge, they will create a Warp 10 shockwave of infinite destructive power.
