In the Otherworld of Theia, the History Sphere, which is comprised of Earth's history, has been smashed by Warlock Brogan in an act of revenge. He has stolen five discs and his aim is to change world history and cause chaos in the human world. The History Keeper, a wizard called Hector, must seek the help of Olivia, an eleven year old human girl in order to retrieve the discs and repair the History Sphere.

Olivia, her little dog Archie and her companions, a dwarf, an elf and a pyskie, must travel back in time to various pivotal world events in order to recover the discs. They must defeat all kinds of monster and demons, sent by Brogan to prevent them from securing their objective. Can Olivia and her unusual friends work together to find the love, friendship and courage they will need in order to overcome adversity, recapture the discs, complete the Sphere and allow earth history to remain unchanged?

It will be a huge challenge but one that only Olivia can accept.
