That would be an understatement. Yes. This of course after they also would go through different planets and experiment on the native races of that planet to create a warrior.
Basically.
We prevented the world from being split up and so that future is no longer a concern. As for preserving the past? It doesn't seem that way. We've been moved to another time but I'm not sure where we've ended up just yet. So while we stopped one plot it seems another in a different decade is still in the works to make up for the foiled plan.
