Somehow, the Children of Raxxla leader, Salomé, knows the big picture of what they're looking for out there and the Federation framed her in order to imprison and silence her. Her followers have caught onto this but do not know the big picture yet themselves. Their hope is that once they do, the fact that she was framed will become obvious. They don't actually know where to send pilots, only that they want to send to the same places as the Federation and hope those pilots give them the information instead of the Federation.
How this is going to play out I think is that we're not going to know the big picture answer after this CG. This is going to give us the locked door so to speak and another later piece of info will give us the key to opening it. Whatever is found in these areas isn't going to work for us; it's not going to interact in a meaningful way. Something later will tell us how to open the door. At that point, pilots will have to bring either some knowledge, a key, or a critical mass of items or item back to these areas
It is not the Federation that imprisoned Salomé, but the Empire. She was likely framed for the attempted assasination on Senator Patreus to prevent her from digging deeper into the secrets that the Federation and the Empire are trying to hide together.
Therefore, if the Federation wins this CG, it is likely that the truth will be lost, maybe forever.
