Star Trek: 10 Things We Now Know About The Temporal Wars

10. Na'khul

In a way, the Na'khul come in at the end of what we know about the Temporal Wars. They make their first appearance in Zero Hour, though are featured primarily in Storm Front. They are a faction in the Temporal Cold War who believe that time travel is their right, regardless of the effect to the timeline.

Vosk, the leader of this faction, escaped his time on a one-way trip to an alternate Earth, in 1944. Limited to using materials of the time, he allied his group with the Nazis, thus allowing the latter to effectively win the second world war. This bargain allowed Vosk and his team to work on finding a way home to the 29th Century.

Lt. Daniels managed to transport Enterprise back to this point in history, with Archer finally ending the Temporal Cold War by preventing Vosk's return to the future.

Though the Na'khul have yet to appear in Discovery, or even be named on-screen, this gives the audience a definite end point to the war, though it is far from the final word on the topic.
