Suggestion: Galactic War Fifth faction: The Pregenitors

what if a fifth non-playable faction is added to Galactic War (only in Galactic war), and i would be the progenitors.

so here is my idea/suggestion

the progenitors only appear after the player(s) defeat all enemy factions.
the start with good+ tech
when they appear the instantly conquer some of your controlled systems
the are always hostile
there commanders are the progenitor commander and commander based on the progenitor.
some planets have mark of their existence.

what do guys think of this idea?

Eh, save it for an expansion or something i'd reckon.

From a lore perspective it makes little sense.
They were either brought to extinction or ran so far away that going back wouldn't be a sensible choice.
Not only that, but the goal of the Revenants is to find the progenitors, it's doubtful they'd kill them, even if attacked.

Unless by progenitor you mean a faction of progenitor commanders, in which case, maybe.

Cool idea but definitely saving the progenitors for something down the road.

I'm hoping the that something down the road to be quite interesting and awesome

Yes. Yes! YEESS!!!!

Also, I am actually doing a campaign story myself. It is so complicated, it actually is Metal Gear Solid esque in it's sudden changes. However, it does take place in a distant part of the timeline, and implies ambiguity to the events of the past.

Like the reapers in mass effect?

Let's not mention those..... things...

The faster we move on from ME the faster we can all forget, then the healing can begin.
