Once upon a time there was a Lord McDuncan who stole a precious diamond. McDuncan blamed the king and managed to dethrone and succeed him. The old king was thrown into the dungeon maze beneath his castle. McDuncan also hid the diamond in the Dungeon, hoping no one would find it there. According to a legend, a dragon lives in the dungeon.

You are the king and you have to find the diamond and a way out of the dungeon, in order to throw out McDuncan and reclaim your throne.
