On Muraco, also called The World of The White Moon, the main mission of every young dragon is to find its protective stone which the dragon will carry on its forehead for his entire life. This gemstone strengthens the young dragon's personality and helps him to find its place in the dragon-world.
How to find this stone is shown to each dragon by the Oracle named Adama.
While Draco, a member of The Council of The Seven Stones, and his mate Stella chase the unscrupulous Charc who kidnapped their son Sparkle in order to use his protective stone for himself, the other five siblings try to find their gems.
