“Prophecy” is episode fourteen of season seven of Star Trek: Voyager.
Voyager is being fired at when Captain Janeway enters the bridge; the attacker has cloaked again. When it decloaks, Tuvok says the disruptor blast has a Klingon signature. It decloaks and opens fire again; the ship looks like an old design. As in, TOS era. Tuvok says it’s a D7 class cruiser; the last D7 was retired decades ago, according to Tom. Chakotay says that a vessel that old will have antiquated technology and Seven is told to do a metaphasic scan to penetrate the cloak. The cloaked ship is fired on and onboard the captain is told the cloak has failed and shields are offline. The Federation vessel is hailing them again. The captain says to answer and Janeway tells him to stand down. He replies he won’t surrender to sworn enemies of the Klingon Empire.
Captain Janeway tells the Klingons that the Federation and the Empire signed a peace treaty more than 80 years ago and if she’s not mistaken it’s still in effect (though there was a point when it wasn’t). Even if she’s lying, the Klingon ship is no match for Voyager (a ship capable of going head-to-head with a Federation Constellation class 100 years ago is rather puny by today’s standards). Janeway wants to discuss the matter and eventually persuades him by saying her chief engineer is a Klingon.
The Klingon captain, Kohlar, beams over and is escorted to see B’Elanna. He becomes very interested on seeing she’s with child, and quizzes her about the conception. He decides he has to return to his ship and assures Captain Janeway he won’t open fire again.
Back on the cruiser, Kohlar is telling the other Klingons that the scrolls say two warring houses will make peace; the Federation and the Empire. He believes the child is the one written of and the day of their separation is at hand.
On Voyager, Harry reports the Klingon’s core is breaching and Kohlar says more damage was done than thought. There’s not enough time to fix it and all the Klingons – 204 of them – are beamed into a cargo bay.
In the captain’s ready room, Tuvok tells Kohlar that the containment failure was not caused by Voyager‘s weapons. They know a self-destruct sequence was activated. Kohlar says that was the only way to get onboard Voyager. More than 100 years ago, his great-grandfather was part of a sect that believed the Empire had lost its way and followed a sacred text to a distant part of the galaxy where they would find the kuvah’magh who would lead them to a new empire. B’Elanna’s child.
B’Elanna and the rest of the senior staff are told. Tuvok is concerned about the security threat posed by the Klingons, and wants to confine them to the shuttle bay. The captain disagrees, but agrees they need to be kept away from anywhere sensitive.
The captain enters the mess hall where the Klingons are dining; Neelix says they enjoy his cooking. Then a Klingon man and woman start to quarrel and Neelix tries to intervene. Then Harry successfully intervenes and the woman decides he’ll make a worthy mate.
Neelix arrives in Tuvok’s quarters; they’re bunking together. Tuvok is the only one who didn’t pair up and Neelix knew he wouldn’t mind. They’ll have fun. Tuvok should have probably paired up with Vorik, a fellow Vulcan, or Seven, who when channelling a Vulcan personality behaved no differently, instead of not doing anything.
B’Elanna is heading back to her and Tom’s quarters from engineering. There are Klingons outside, so she beams directly there. Tom reminds her that she felt uncomfortable being the only Klingon. Now, they have lots. Then the captain arrives; ten of the Klingons are going on hunger strike if they can’t speak to B’Elanna.
The meeting doesn’t go as well as it could, because B’Elanna’s blood is not pure. They’re even less happy to hear the baby is going to be even less Klingon. Afterwards, Kohlar speaks to the captain; he wants B’Elanna’s help. Truthfully, Kohlar doesn’t know if B’Elanna’s child is the kuvah’magh or not. He just sees a chance to end this wandering and suffering. The scrolls can be interpreted to make it seem B’Elanna’s child is the kuvah’magh and the other Klingons convinced. However, T’Greth, at least, is extremely unhappy.
So, Voyager‘s crew is outnumbered by Klingon religious fanatics who may or may not think B’Elanna’s child is the kuvah’magh. And Harry is being pursued by an amorous Klingon woman a foot taller than him.
