Slashing Blade
Future research society: Human run society that knows about the domain creature’s control, and is working with them to try and etch out what they can do to give humanity as much of a fighting chance as they can without crossing the line. They also try and get information from the domain controlled places to get advancements to try and use their own tech against them that obviously failed in the end. Or they are a group that thinks they’ll lose anyway so they’re trying to at least let some survive.
