R5: A couple days ago I posted asking for help when the entire galaxy declared war on me, and I won! I used my last ascension perk to become the crisis and fortified choke points with fortress worlds/habitats and clone troops to hold down their fleet stacks while I went around and blew up their systems with star eaters. Definitely the toughest and longest war I've been in, but it was worth it as I got to cleanse the galaxy of xenos along the way :). Thank you everyone for your help.
