A bad enough plague can wipe out an interconnected society if it moves quickly enough. Again, this is one we see irl (historically and currently), albeit on a smaller scale and it doesn't make anyone into zombies. Specifically a kind that can turn your own defenses against you. If two opposing factions each gain enough power in your precursor race, they might turn those planet destroying weapons on their own people.įinally, plague. No chimps or dolphins are rising up against us, but we sure can kill each other. It's also one we see with our own species. This is probably the most common one, I would argue. But it's still not that big of a threat to a galaxy spanning empire that's either powerful enough or benevolent. Star Wars KOTOR shows this one, as does Halo (kind of) with the Precursors being replaced by the Forerunners. Second, an uprising from your enslaved population. I can only think of the Yuuzhan Vong from star wars and they lost. Why travel a lifetime across empty space to fight someone just as strong or possibly stronger than you when you have near infinite resources in your home galaxy? This one is pretty rare. Considering the massive distances between galaxies, and the amount of resources in your home galaxy, this is rarely an issue. If your civilization reaches a level where they have instantaneous communication across the galaxy, can casually harness all the power of entire stars, can move across the galaxy in a matter of days or even hours, and have weapons capable of killing billions in a single shot then you're pretty much untouchable except for four things.įirst, an attack from a rival power from another galaxy. I'd actually lump self replicating machines into this too because they function basically the same way. Conventional wars can be won, but an enemy that self replicates or assimilated your soldiers and tech can use your own civilizations advancements against you.īecause once you reach a certain size and level on the tech tree, nothing else can really touch you. TL DR: Because it's the most surefire way a galaxy spanning empire can get destroyed. The others im less familiar with but that should show it's more than just psychic space zombies eating everything. The infection is just a rogue wmd at the ends of the origin system and more a nuisance than a threat. In warframe unless the situation has changed it's a combination of super advanced artificial intelligences and a space God that wiped the orokin out with warframe pawns. Evolutionary path is destined to always end in necromorphs because it started with them. All life is descended from them to evolve into a food source like us humans or is wiped out by the moons like the dinosaurs. In deadspace the brethren moons seed life across the universe and feed on it. The forerunners were outplayed by a species that's possibly billions of years old and some fluke in genetic coding They left themselves devolved as a trap to punish the forerunners and simply devolved too much to limit their carnage to one species. In halo the flood are the remnants of an ancient species that could travel between galaxies and harness near infinite energy and power. The fey (specifically the eladrin) are the ancestors of the elves but both still exist without any devolution.You're drastically oversimplifying the situation. They either created the lesser races themselves or made them through procreation over time but the original races always stayed. The Batrachi aren't really clear on the subject.īut seeing as how it's still questioned as to whether or not those three creator races are still around in some way I would say that they definitely didn't devolve. The Aearee are said to be creators and ancestors. The Sarrukh basically took scaly, reptilian animals and monsters already native to Abeir-Toril and modified them into sentient beings. The fey obviously still exist in the Feywild but don't have as much of a connection to Faerun as they originally did. Aearee created aarakocra, kenku, and other bird like humanoids. Batrachi created the amphibiods like bullywugs, doppelgangers, kuo-toa, and other shapeshifting or amphibious or fish-like races. Sarrukh created the yuan-ti, naga, lizardfolk, and similar. It's said that the sarrukh, batrachi, and aearee created/produced offspring the lesser races. The other creator races are said to either be extinct or living in very small numbers hidden somewhere in the world. Assuming you're talking about Forgotten Realms, the five creator races are sarrukh, batrachi, aearee, fey, and humans.
