Cerulean Stone

The cerulean stone is a stone found in the Eastern Lands that turns into sand by the touch of water and moonlight. It is with this stone that George confirms his theory of making a machine fly.

Apperance
The stone can also be found as blue sand or floating blue liquid. If the moonlight and water touches the stone it will first transform into floating liquid, and then blue sand.

Usage
As a stone it has no known use other than it can turn into other forms.

As floating liquid it can be used as fuel to make machines fly.
