LONG long ago...
Well, more like twenty years ago...
Belle married beast in front of their closet personal friends.
Big cake.
So, yeah instead of a honeymoon beast united all kingdoms together and got himself elected as King of the United States of Auradon.
He rounded up all of the villains and sidekicks...and booted them off to the Isle of the Lost, with a barrier to keep us from getting out.
We have no magic, no wifi, and no way out. Or so we thought...
