My best idea for the sequel for my nation is that the ZP collapses from certain events (and if keyguy is willing for me to throw in illegal/legal immagrants at his planets during a certain crisis, that would be dandy) and only a select few planets remain (they're basically shepherds and farmers, except for a select few cities which remain significantly intelligent, but do not have the resources or power to use FTL or make a basic ship to travel). The colonies on other galaxies are cut off from the main systems, so they are either A. Eradicated B. Fended off for themselves and now survive in a 21st century like climate C. Have formed their own systems but remain to themselves as they can't go to the main systems, or maybe another option, I don't know. This would leave the gods to allow one, final, Hach species to develop themselves (will make this later) and they basically search the Milky way on clues of the ZP remnants. They basically want to find the history of their moral codes, species, religions, etc and will do anything to obtain the information, whether it would be trade, diplomacy, or invasions and eradication of the other species. It would be like the Covenant in Halo. so to speak. And I was gonna have more Hach species, but at this time and since there wont be numerous galaxies, I'll leave it at 3 (now four possibly)
