Too much had happened in one day!
At first, multiple powerful first-rate states declared their intention to secede from the unified human civilization framework that had originally been setup by the Mech Trade Association and the Common Fleet Alliance.
During the time of the Great Severing, most people never questioned the assumption that the mechers and fleeters would remain in charge of the humans that could no longer return to their home galaxy.
Their circumstances drastically changed, but inertia and familiarity caused many humans to accept the reign of their familiar overlords.
Even when the Red Association and the Red Fleet started to take on their own identity and begin to make adaptations that their parent organizations would never consider, they still represented the old status quo.
No more.
The decision of so many major players seceding from unified humanity had irrevocably damaged the authority and reputation of the Red Two.
