Bionicle Chronicles

Bionicle Chronicles is the first book series set in the Lego Bionicle universe. Although it was published in 2003, it summarizes events that occurred in the first story arc that began in 2001. When the second story arc began in 2004, the Chronicles series was replaced with the Bionicle Adventures series.
