Rau

"The lead Kikanalo gave an angry snort as it closed in on Nokama. The Toa of Water responded with a similar sound."

- Narrator, BIONICLE Adventures 4: Legends of Metru Nui

The Kanohi Rau was the Mask of Translation. The Great Rau gave its user the power to understand and speak in almost any written or spoken language. The Noble Rau, however, only lets the user understand writing and symbols. Both the Great and Noble versions allow the user to understand the intention behind carvings.
