The door to the palace is open, but it's too big to open. It's an eclipse, which means that the doors of the past have been opened. The door is now 400 years in the past. There's another door that's opened, and there's a bunch of other things going on. It turns out that the door is actually an ancient machine that mixes time with celestial magic. It used to be able to move through time, but now it can't because the moon is warping the magic. This is why the doors are opening and closing so fast. The other thing going on is that there are rocks moving through the door. It looks like they're coming from an ancient time when the world was ruled by dragons. The doors are closing and closing, and the other thing is that the world is going to be swallowed up by the wrath of the dragons. That's what the other guy wants, too.
