The Rahi are the beasts of Mata Nui and Metru Nui. They have their own powers, strengths, weaknesses and enemies. Some live in the protodermis seas, some fly through the air, and some slither below ground. None of them are like anything you've ever seen before. Now you can learn everything there is to know about the Rahi. Some of them will be new, some of them will be familiar, but all of them are unique. Filled with never-before-seen photographs of actual models, this book is a one-of-a-kind guide to the Rahi.
