Karzahni (Location)

History
Karzahni is the mythical Matoran land where lazy and poor workers were sent and tortured by its ruler, whom the land was named after, since the Matoran have forgotten the land's real name. The location itself is very strange.

As revealed in BIONICLE Legends 2: Dark Destiny, Karzahni was originally intended as a place to repair Matoran, then Karzahni the ruler was supposed to send them back. Preferring despair to repair, the ruler gave the Matoran weapons instead to help them defend themselves. After doing this he sent them to places like the Bionicle Mainland to live rather than sending them back to where they came from. It was also revealed in the same book that there are a lot of Manas in Karzahni. Karzahni was destroyed when Gali summoned a tidal wave to fight Icarax. All in the realm was destroyed except Toa Lhikan's Noble Hau

Geography
The ground screams at every step and it constantly emits heat greater then that of the Great Furnace of Metru Nui. Other land features include volcanoes that spew burning ice, and waterfalls that are made out of dust rather than water. And if a Matoran is too lazy and sits down, the rock which the Matoran sits upon will turn the Matoran into a statue.

The realm used to be accessible by boat or airship. However the waterways dried up and now it can only be reached through an overland path infested by Manas.

Trivia
Karzahni is the birthplace of the Dark Hunter codenamed "Devastator", who is reputed to have emerged from a fiery crevice in the region.

Karzahni has long been watched over by Makuta Icarax. Despite the fact that the Makuta were once guardians, Icarax never rescued the Matoran; he felt that workers bad enough to be sent to Karzahni were worthless. With its ruler gone, Icarax sought to conquer Karzahni and establish a power base there.However, the Toa Nuva confronted him (after evacuating the Matoran) and, in desperation, Gali Nuva unleashed the full extent of her water power, completely destroying the realm.
