The Fleet's Origin
The World of Tree Spirits.
It's a world I didn't recognize. Probably, it's one of those worlds where the Hero wasn't from our Special Class and it had been saved without my assistance.
Either way, it's undeniable that it's connected to Earth. If they're not going to conquer it, they're probably going to use it as another foothold to arrive there. Maybe they had other plans but that's why we infiltrated them.
After more probing when I rejoined Erin to investigate, the ones in the perimeter were given limited information. They're just there to set up a barricade and to stop any unaffiliated Space Vessel approaching the area from snooping around.
