So my third game and the Unbidden appeared a nice distance away from my empire and started royally tearing everyone up. Everyone invites everyone into a Federation excluding me (because I'm repugnant) to combat the new threat.
I am however allied to one guy and the idiot start to antagonize some super advanced fallen empire (Keepers of Knowledge), who then declare war on him, and in turn declare war on me.
Now I have an super advanced alien race flying around my empire melting everything with their tachyon beams.
I tried to reload and back out the alliance but said something about upsetting other races so I couldn't leave and now I'm dead.
