We are fully aware about the mixed relations between the IMG and Crayter. The IMG doesn't really need these former slaves as they already have plenty of potential recruits themselves and they lack proper facilities to house them. But if there are parts of the IMG who care about the wellbeing of these former slaves, then shipping them to Yuma is the lesser evil of all available choices.
Yuma has developing infrastructure and civil society, it's habitable and despite CR's faults, they are likely going to treat them better than the Cryer or Gallia.
If that is the intent then I recommend rewriting the original post both to make it clear that it is publicly available knowledge that GN/GNI and Cryer are trying to get their hands on the liberated slaves explicitly for experimentation purposes and that the options besides Yuma do not have the capacity to take care of them.
This wouldn't exactly be something that's public knowledge at least as far as the GNI side of things is concerned, I discussed this with Jammi back when the event was in writeup stages, and he approved of the idea of Gallia promoting this as if they were genuinely going to take care of these people. I doubt Cryer would be saying the quiet part out loud either, but I'm not sure how public their experimentation on Outcasts on Atka was.
