I want something convincing. if it has to be the typical robots, so be it. Atleast it explains why a race that had spent its entire existance conquering would fall like a deck of cards.

well i'm actually thinking there's a HUGE PLOT HOLE in sins lore actually making it very possible there's at least another 3 other factions or subfactions rather than the tec , advent, vas and the vas exterminator. the first 3 factions may indicate some of this factions.

1.ok let me straight this out, as we all assume the traders are descendants from humans who venture out to the space and after thousand years may have forgotten bout Earth. Did they leave earth cuz its already too poluted or its been destroyed by whatever means? if the earth is poluted and later destroyed, i would suggest the humans left there was badly mutated and later leave earth before it was destroyed making it the 5th faction OR the humans that venture out to space SPLIT into several groups which one survived and finally they become the traders.what about the other groups that split and after being exposed to cosmic radiation and adapting to alien environment they mutated their human genetics into something else?that idea alone opens many possibilities?

2.for advents we all knows they origin from a broken people who sought spiritual enlightment and develops their practices even further. QUESTION IS : are they developing all of that by themselves or they were taught by someone else?the advent collective mind DOES NOT come from the sky in an instant yes?it could be the advents themselves being taught by another faction for developing their collective sense?not to mention something DAMN STUPID about the opening story bout traders kicking advent's ancestors from their world without thinking they WILL COME BACK FOR REVENGE?its that a smart thing to KICK ppl out from their house and thinking their not coming back for PAYBACK?that stupid act actually opens a possibility that there another faction that is strong enough to influence the traders just to spare THE TWISTED HERETICS and exile the advents! whatever this faction is they also have their own collective mind that is comparably different from the advents due to their separation during the exile making them a possible 6th faction.

3.for vas, we all know they didn't create PJIs but found it and succesfully replicate it using nano tech.that fact alone opens a 7th faction that once inhabits the vas space at the time when vas are ummmm i dun know how to rephrase it maybe alien undeveloped monkeys as we humans?

well thats it for now , i'm thinking bout how will this 3 factions interacts with the other 4 factions?

Robots would kill Space Ponies (although having pink capital ships with unicorn stickers would be awesome...)

Yoshimi Battles the Pink Robots

i should have listened to Darvin...

That'd be interesting, but not new...

Actually...there's not much new that can be done...

Well... If we're offering up old ideas for cannibalization, how about a race of all anergy beings like the Drej from Titan A.E.?
