While I agree on the possible misconception for the TC between drifters and biological drones (based on their tech, the frontier between bio and tech seem very small). But the fact that they do say that at least some triglavian works with “deviant automata” and that we DID saw rogue drones work with TC. Unless new data, it seem likely then that the deviant automata are indeed rogue drones.
Sir, you enter my field of study there ^^
I can only redirect you to my work on gravitational waves.
But to keep things simple, Abyssal deadspaces pockets are “gravitational maelstrom”.
The Exact “where” is irrelevant but could be calculated based on gravitational waves.
To be honest, I would gladly have your help on the matter to try hypothesis HOW those pockets are linked one with another.
