Stardate Unknown: The timeline has been disrupted, and the Federation stands on the brink of war. It's up to you to restore history — no matter the cost.
Things are heating up with the Tholians. Monitor stations are detecting large fleet movements toward Federation space, and they're refusing all of our diplomatic hails.
We're doing all we can to prevent a war, but it's not looking good. I want you to join a task force I'm assembling.
If this goes south, I want my best people on the front line when it does.
