Final Quest

You take the scale out of your pocket, and hold it up. It suddenly begins glowing with a green light. Then, ropes of light come out of it and wrap around the ghost.
The ghost falls, and disappears almost immediately.
Two stones float towards you, and you take them out of the air.
"This castle has served its purpose," the king says. There is a flash of blinding light, and the castle disappears.
The green dragon returns to his normal size, and looks at you. "Where do you want to go now?" he asks.
