Grey Belt

The Grey Belt (formerly known as the Green Belt) was a devastated region of Voya Nui.

History
The Green Belt was originally a vast forest that covered most of the outer regions of Voya Nui.

At some point between 99,080 CMT and 100,060 CMT, Zev Raregroove travelled to the Green Belt of Voya Nui, only to be followed by Blackout aboard the Nemesis. Blackout defeated several Hollows and proceeded to bomb the Green Belt out of existence with the Nemesis' arsenal of fusion bombs, which prompted Zev to rename the devastated region the "Grey Belt".

As part of their mission to save the life of Mata Nui, the Toa Mahri intended to sever the cord that anchored Voya Nui to the base of the Matoran Universe in order to return the island to its original position in the center of the Southern Continent. Due to the fact that it was later established that Shinobi-Nui was left as the only remaining island on the surface of Aqua Magna after the destruction of the island of Mata Nui, it can be assumed that the Toa Mahri succeeded in this part of their mission and Voya Nui was returned to its original position in the Matoran Universe. The Grey Belt's status after the Matoran Universe was dismantled and rebuilt into Darkmount is unknown.
