The story begins with a substance known in the game as black fog. This fog is known for consuming people, towns, and other signs of civilization or life, nothing ever to escape from within. In Lost Kingdoms, the fog invades the land of Argwyll, home of the main character Katia, who is also the princess of this kingdom. The fog has been terrorizing the land for a long time, and Katia's father - the king - eventually ventured out to help try and deal with the deadly substance. However, since her father hadn't returned in some time, Katia soon leaves to find him.
