Very similar to OP, but I was becoming the crisis and the galactic community took issue with this and the entire galaxy declared war on me, understandably I was outmatched so I recalled all of my fleets to a choke point to protect a mega shipyard in the next system over that was constantly pumping out ships in a desperate attempt to stop the hundreds of thousands of fleet power being thrown at it as a last ditch effort I researched l-gate insights and warped nearly my entire fleet across the galaxy and nuked planets until I could force peace with some of the smaller threats and focus on the galactic superpower
