The Mothercrystal at Stonhyrr falls. The plan Cid started and Clive inherited is moving forward, and each Crystal that breaks is a small proof that the world's infrastructure is not permanent, not sacred, not inevitable. The people who built their power on Crystal control told everyone it was the natural order. It cracks like anything else.

Freedom in FFXVI is not a condition but a process. The Bearers who are freed when the Crystals fall don't suddenly have a world that welcomes them. They have a world that no longer has a structural justification for their enslavement. What they build with that is the question the game leaves open, the space on the other side of the ending that the player has to imagine.
