The Buronakx Chronicles is actually two stories about the top scientist Spherian (A species that are basically the Great Beings), Buronakx: Back to Before, and Stars of Sorrows. Back to Before is about Buronakx's past life during the creation of Mata Nui. Stars of Sorrows is about Buronakx's present life after the Shattering. It's like a pattern, one chapter is Back to Before and the next is Stars of Sorrows and so one.
