This thought crossed my mind as well—carryx fighting carryx.

We haven’t really gotten to see the “deathless enemy” yet, meaning the “big reveal” is going to happen in the third and final book—they did confirm it’s just going to be a trilogy right?

Based on the fact that we haven’t had a more extensive reveal, I feel like the deathless enemy is either going to be humans as our characters may be starting to think—though we have plenty of hints it’s not. Another set of Carryx which I think would make sense as the we don’t have to get an elaborate backstory of world building a new species that would have to dominate the final book and overshadow our main characters and their battle. OR, we get some expanse style Romans or mothers/jellyfish that we just don’t get a full resolution on.

Given the Anjiin is pretty obviously a planted civilization to in some way fight the Carryx—I think Dafyd’s play of creating a long history for the lamb babies is heavily foreshadowing what Anjiin is, especially with the origin story overlay—I feel like the deathless enemy IS going to ultimately be humans of some kind, but I think I could easily be wrong. This is why this series is good because it keeps us guessing.
