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."

- Narrator, Power Play

The Kanohi Elda is the Mask of Detection. It allows its user to see nearby hidden beings, such as a Kanohi Huna user; it also detects the Kanohi Ignika's presence, indicating how near it is through increasingly strong headaches. The only difference between the Great and Noble versions is that the Noble only allows its user to see hidden beings; there are few Great Kanohi Elda because its primary purpose is to locate the Mask of Life. Kanohi Elda are always on at a low level.

Example Usage
Hahli's Great Kanohi Elda let her see and hear Matoro's spirit when he had released it in Power Play. She also inadvertently tracked the Kanohi Ignika in the same book.
