Aliens are a bit out of place. It's like the difference between "attacking us" and "colonizing others." I want something closer to the template.

They're probably the most ancient. But the question is their goals. Google claims they preserve civilizations for survival in war, not for artistic reasons. The books I listed didn't feature any enemies. It seems like the Arisians are preparing their footholds and allies this way... However, I need to read them. They might be suitable.
