A young hero travels by train to his grandmother’s house in a village after his parents send him there to help prepare for an upcoming holiday. He would rather be at the beach, surfing the net, or playing a new computer quest game, but he goes anyway.

When he arrives, no one answers the door and the house appears empty. He goes inside, explores the attic, and finds souvenirs from his grandfather’s travels to other worlds, along with a strange metallic device hidden in a closet.

The device is a dimension machine that can talk and show animated movies. It tells him that his dimension will implode and that Merlin is the only one who can save it. Merlin was defeated by the Wizard of the North, banished to a remote dimension, and had his staff smashed into five pieces scattered across the dimensions.

The hero agrees to help and can use the machine to travel between dimensions in search of the staff pieces. The grandfather, who really did travel to many dimensions, became the Master of Dimensions and leads the Dimension Council. He had sent his first dimension machine to be found by his grandson.
