Elda

"Jaller looked up to see that she was facing away from Matoro, apparently having a conversation with the empty air. He wondered for a moment if Hahli had gone crazy."

- Narration, BIONICLE Legends 3: Power Play

The Kanohi Elda was the Mask of Detection. It gave the user the power to detect the presence of nearby hidden beings (such as a Huna or Iden user) and track the Kanohi Ignika. Few Great Elda existed, as their primary purpose was to track the Kanohi Ignika's location. The Noble Elda only allowed the user to see hidden beings. Kanohi Elda were always on at a low level.
