BIONICLE: Encyclopedia

Bionicle Encyclopedia Volume 1 features all of the characters, places, and things from the 2001-2005 story arcs. This includes the Toa Hordika, the Toa Mata, Mata Nui, Makuta, Takanuva, the Brotherhood of Makuta, and more. It also features a short story about how Nidhiki became evil, called Birth of a Dark Hunter and a pronunciation guide, color pictures, and as a bonus in the very back of the book, a page of Bionicle stickers. This Encyclopedia came out in 2005, and a sequel was later released, named BIONICLE Encyclopedia Volume 2.
