And just like that, they just fizzled out.

I'd have expected at least an explosion or some reaction, but nah. This was the most boring "last boss" ending ever. The representative of the alien faction, whatever they were, behind the US dems and abortion, started yelling and throwing papers around in the galactic council. Then when no one listened, started calling the beast mining group "irrelevant" which made everyone wake up, because every alien race in some way relies on mining for minerals. Then the seething "democrat" called the council "corrupt". The secretary, from the non-humanoid group which is the largest (seemed like a cthulhu kind of being) banged his club and said "order!" then suggested to "permanently terminate this representative for disturbing the order" and asked if there was any objection. No one said anything, so guards then took the fuming alien outside and executed him.

Some while later, a new representative from that galactic area came in, and this time it was a beast from the federation. Turns out the miners took matters into their own hands than invaded the place, then took over the ruling role. And that's that.
