Quest for the One Perfect Diamond:

Many centuries ago, King Arthur sent forth his knights to find the one perfect diamond as a gift for his queen. Sir Grenvell succeeded. He found the diamond embedded as the eye of a stone idol called Orac. Drumgargs, evil, black-robed priests who worshipped Orac, attacked Sir Grenvell. He killed them and took the diamond. A dying priest whispered a curse: She who wears the idol’s eye will surely wither, age and die. King Arthur ordered a golden necklace crafted to display the diamond. When the queen first wore the necklace, the curse proved true. She quickly grew old and collapsed, overturning a lamp and starting a raging fire. Alfie, the court jester, rescued the necklace and escaped through a concealed door into the Underworld.

Fast-forward 1000 years:

While on a tour of King Arthur’s castle, three children - Lucas, Claira and Andy - find a hidden door and unwisely enter. The door closes behind them and they are trapped in the Underworld. Following the sound of chanting, they stumble upon Drumgargs worshipping Orac. The priests almost capture the children but Alfie rescues them and hides them in his secret cave. The little jester can never leave the Underworld. He can, however, guide the children to the hidden door where they can escape. On the journey, Claira is captured by Drumgargs who plan to sacrifice her to Orac. Using the diamond necklace as a lure, Alfie draws the priests away from the idol, hoping the children can escape.

Do they escape?
