-1. But what kind of charge? Is he charging the guy telling him? Is he charging the Tyranids? Is he charging his weapon?
I think we or the Imperial Trust Guard could probably fill all of the uncorrupted roles a commisar could fill by using unit champions and stealth commissars(internal security?).
The idea is probably much more use to the Trust Guard than us.
-2. Who do we talk to to make this possible?
Can we just say we brought it up with Klovis Ultan and call the idea distributed for further examination without needing to take any further in-quest action, or do we need to set up a meeting with the Inquisition, Security Council and governor of Niflhiem?
Most of our Rogue psykers are as such because they fall to Chaos, and a big chunk of our ability to keep them down is in the forces we array against them. Also I get the impression The Thread didn't want to trade lakes and tech to the Sirens for runes because we'd eventually get them anyway so if I want the lakes idea to be valuable I need to think of an alternate use.
-3. What would trading with the Avernite natives for mercenary forces to fight Rogue psykers cost?
They're essentially Chaos anyway, so it could be pretty cheap.
I'm thinking something a lot like our Primaris response forces maybe? It depends a lot on what kind of role they're best able to fill and whether they have any special uses in this context. We've fought alongside them against Chaos invasions in the past, so this isn't an extreme leap.
-4. Is the Djinn Skein Gladatoria an MIU thing where the simulation exists only in the mind of the soldier, or an environment thing where the soldier moves their body in an emulation environment to experience the simulation?
Because if they're stationary the right medical tech should allow us to pack even more soldiers into a small space in our transports. In fact this idea might be worth looking at for tech development anyways. The effect would be degraded by the volume and maintenence requirements of their equipment, but it might be useful.
They're probably mobile if the system gets used on Avernus though.
