Reunification of Vale

"Now that Vale is reunited back into a kingdom, it's a good thing that Vale also has a presidential republic, yet the president of Vale's not gonna be a head of state, like what others do, but is gonna be a head of government. I'd make sure that the king of Vale's still the head of state."

--Su Ji-Hoon, Rebirthing Vale

The reunification of Vale is an event where Vale gets reunited into a federal presidential republic under a constitutional monarchy while King Vi III remains in his reign. It takes place after the Third Beacon War.

This event doesn't mean that Vale's monarchy got abolished, but it gets to be a combined monarchial-republican government instead.
