Keeper of the Keys (Fight for the Universe)

Charles is excited when he begins attending a magical school, and his joy only increases when he finds himself riding his own Plythegon. However, as wonderful as the magical world is, it is far from safe. Time seems to freeze as Charles passes over a river, and berserk monsters hide in every corner. Once Charles learns the truth about his uncle, he realizes that the fate of the universe is in his hands. To stop his uncle, Charles must travel to the galaxy room. To enter, he needs the magic key, and the guardian of the key is a mysterious man called the Keeper. Charles must learn all that he can about magic and about his uncle to be able to save the world. In this ultimate battle between good and evil, Charles must use all he knows to defeat the Dark sorcerer, lest the world be covered in darkness forever.
