I just know that the brethren moons seek to create more of themselves to strengthen the signal.
I think they keep the necromorphs at bay for a bit so the "cattle" can build more marker copies, especially for far flung space faring races. More opportunity to spread the signal. I can't say for sure.
the endgame is expansion, that's the most I can get from it. I haven't closely examined the audio and text logs though.
It's starting to sound like a horror themed mass effect, with the cycles and extinction events.
