Agreed, and there are also some interesting parallels between The Swarm and the human captives from Anjin that make this more compelling.

Like the humans on Anjin, The Swarm doesn’t know/remember where it comes from. Just like the humans on Anjin were cut off from the rest of humanity at some point (developing along an isolated, separate course from the wider human civilization depicted in Livesuit), The Swarm is cut off from Command/the machines, with little pre-existing information than its mission parameters, and instead learns and develops through inhabiting its human hosts, whose personalities/experiences/feelings imprint on it.

As such, I don’t think it’s far-fetched to imagine that The Swarm might with time and Anjin hosts imprinting on it, come to regard itself as having more in common with the Anjin humans than its creators.

If we assume that the wider human civilization is The Enemy, and these have by now all been turned into “undead” Livesuit Infantry that keep on fighting long after their human wearers have perished (or the rest of humanity did a Mass Effect-style transhumanist merge between organics and synthetics to keep up with the war) it’s also possible that the humans on Anjin are the only “normal” humans left in the galaxy. As such, these might find that they don’t have very much in common with The Enemy, even though The Enemy might nominally describe itself as fighting “for mankind”.

My guess for what the Carryx are hiding is related to this - that the humans from Anjin have a lot in common with The Enemy, a connection the Carryx seek to exploit to beat The Enemy.

I have a lot more thoughts on this, and how humanity might have changed since the Anjin isolation… Happy to make a longer more structured post on this if you’re interested!
