Crazy theory - probably spoilers ahead
I’ve been mulling over this theory and will see how well I can explain and flesh it out:
It’s The Captives War, and so far we’ve only really heard from the captives, and not the captors. Im sure many of us have theorized that the humans are as much captive to the Live Suits as all the species (human et al) are captive to the Carryx; but what if the Live Suits aren’t at war with the Carryx but rather a parallel to them: an AI like machine? What if the Half Minds have captivated the Carryx? As the instrument of communication - across light years and species, and back - they could easily have captivated the Carryx as much as the Carryx seemingly captivate other species. So ultimately it’s this galactic level battle between two god-like AIs?
It’s either that or hacking the half-minds will be how Dafyd and the Live Suit(s) take down the Carryx.
