Canyon of Unending Whispers

"Side by side, they marched into the Canyon of Unending Whispers. The clang of their footsteps echoed again and again. The sun baked the barren rock for as far as the eye could see. A few Rahi flyers swooped and dove in the bright sky."

- Narrator, Birth of a Dark Hunter

The Canyon of Unending Whispers, also known as the Place of Unending Whispers, is a lonely canyon at the border between Po-Metru and Onu-Metru.

History
During the Toa/Dark Hunter War, the traitorous Toa Mangai Nidhiki was told to lead the the army of Toa into a Dark Hunter trap to win the war. The next day, the hundred-strong group of Toa traveled into the canyon and were ambushed by the Dark Hunters. However, Toa Lhikan then gave a signal and over two hundred concealed Toa showed themselves, surrounding the Dark Hunters. After a short discussion, the Dark Hunters left the Canyon, along with Toa Nidhiki, concluding the war.

Shortly before the Great Cataclysm, mysterious activity had been noted in the canyon - squads of Vahki Zadakh patrolled the area and the Dark Hunters Nidhiki and Krekka were seen taking Toa Lhikan there. While searching for Lhikan, three of the Toa Metru rode a herd of Kikanalo to the canyon. There, they tricked the Dark Hunters, defeated the Zadakh guarding the area, and entered a cave leading to the Prison of the Dark Hunters. The cave was then sealed off by the Kikanalo's roars, which brought down several boulders that covered the entrance.

The canyon was later damaged when a fragment of Aqua Magna struck Metru Nui, causing severe damage throughout.
