The Akashic record is a register of every manifestation in the universe, past, present and future - it is a record of every individual and every action from the beginning of time. The Akashic Records Keeper, referred to as the ARK, was present from the beginning of life on planet Earth, although its location and function has since been lost in antiquity.
Following on from their journey to the future, which they're still unsure happened, Aaden, Tiffany, Fleur, and Ben are faced with an even bigger challenge to their understanding of reality. Not only do they need to consider the possibility of a subterranean world, but also another aspect of themselves, as they journey to a strange new world in search of Aaden and Tiffany's father, a multidimensional Being, also known as Zakeera. Zakeera, a starship commander of the Astar Galactic Command, has been charged with finding the location of the ARK. Traveling back in time, his journey begins with the project rainbow Philadelphia experiment 1943, an experiment with radar invisibility that resulted in the disruption of the time/space continuum. The Nikola Tesla Philadelphia experiment ship, USS Eldridge, physically disappeared from its location in Philadelphia harbor, opening a rip in time that also dragged in an extraterrestrial spaceship. Zakeera's mission, to rescue the pilot of that spaceship, leads him to discover a hollow earth entrance to the kingdom of Agatha Shamballa. His adventures in hollow earth Agatha ultimately require him to time travel into the future, where he finally realises the meaning behind the words of his mentor who, when sending him on this mission, told him that whoever discovers and controls the ARK, has the power to control the universe.
