The Sapphire Dragon

The Sapphire Dragon is a dragon that is made out of crystal. It sleeps in a chamber somewhere within the crystal peak. It is of great interest to the cave dwarves as The Book of Times says that the dragon's breath is the only fire hot enough to forge the ancestral duel blade of legends.

The only remaining key to its chambers and the only way to awaken it was a magic gemstone that long ago fell from the stars. The dwarfs knew of this gemstone and spent many years searching for it.
