AI War 2:Zenith Architrave
The Zenith Architrave
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.
