AI War 2:Zenith Architrave
The Zenith Architrave
A Zenith Architrave is a powerful Zenith clan that exists in another dimension/plane of existence/something. Their dimension is coming into congruence with ours, which allows them to build a Portal to our dimension. They can then transport ships through the Portal and various Spawners. They can only comfortably take "some" planets in our galaxy (the number is based on the congruence of our galaxy to theirs, which is to say "your choice in the game lobby").
A ZA is deeply territorial and they all hate eachother. The all want to expand their territory, but they really really don't want eachother to take too much territory. If another Architrave gets too powerful then all the other Architraves will dedicate a lot of resources to stopping them.
Architrave wars in our galaxy are but a minor skirmish, compared to the giant wars in their home galaxy.
The Zenith Architrave is a Zenith clan that has taken up residence in part of the galaxy. They are highly territorial, and will stake out a few planets as their Turf. Any other faction that tries to invade will be met with very strong resistance.
Usually an Architrave is content to just chill in its home turf, but every so often they will try to expand and take new planets.
By default an Architrave is hostile to everyone. However, if there are multiple Architraves, sometimes they will have a Civil War. This is triggered if an Architrave looks like it's getting "too powerful" to the others. When in the Civil War, Architraves stop being hostile to the AI and will spawn giant fleets to fight eachother. Be careful not to get caught in the crossfire!
Having multiple ZAs makes the game much more challenging, and it can be important to make sure your starting planet is out of their way.
It has been observed that most minor factions tend to either snowball out of control and dominate the galaxy, or else they are very weak. One of the goals of the ZA is to have a powerful faction that is very influential in part of the galaxy, but only rarely tries anything more than that.
