Now we know what makes Ryder... special, and we know why Archon is the bad guy (Unmarked spoilers)

But the Kett in the same situation as the humans in that series???

All will must bend to the perfect truth of The Praxis

For millennia, the Shaa have subjugated the universe, forcing the myriad sentient races to bow to their joyless tyranny. But the Shaa will soon be no more. The dread empire is in its rapidly fading twilight, and with its impending fall comes the promise of a new galactic order . . . and bloody chaos.

A young Terran naval officer marked by his lowly birth, Lt. Gareth Martinez is the first to recognize the insidious plot of the Naxid -- the powerful, warlike insectoid society that was enslaved before all others -- to replace the masters’ despotic rule with their own. Barely escaping a swarming surprise attack, Martinez and Caroline Sula, a pilot whose beautiful face conceals a deadly secret, are now the last hope for freedom for every being who ever languished in Shaa chains -- as the interstellar battle begins against a merciless foe whose only perfect truth is annihilation.

Well, I meant more about the part that the Kett serve the Remnant and that they are the main villain. Or was this already known? I can't remember.
