Mirror Broken Sequel/Prime Universe TNG Crossover Coming In May

Ha, yet another reason I dislike the whole Prophets concept in general. So almighty they refuse to lend help except in the most ridiculous of times for the most ridiculous and incomprehensible of goals. "Oh, we can cause a humanoid to be born but we won't stop his civilization from being absolutely conquered! It's great that people worship us!"

But the whole point is that they don't see time as linear, they knew the Dominion never succeeded because of Sisko, who they helped create. They vanished an entire invasion fleet, which was pretty nice of them.
