Karzahni (Location)

"Went through here, or never made it any farther than this? What are the odds the rest of that Toa is beneath our feet?"

- Takanuva in the path to Karzahni.

Karzahni was 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 had forgotten the land's real name. The location itself was very strange.

History
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 Southern Continent 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 Nova Blast to fight Icarax. All in the realm was destroyed except Toa Lhikan's Noble Hau. Pridak also went to Karzahni to discuss an alliance with The Shadowed One

Reign of Shadows
Tahu, Kopeke, Lariska, Guardian, Johmak, and Krahka assembled a camp in Karzahni where they could organize themselves aganist Teridax, who had taken control of the Matoran Universe. During their debate of their next move, Teridax discovered them and killed a straying Guardian by bonding him with earth and sealing him in a crevice (which killed Guardian). A dozen of Exo-Toa arrived afterward, and the group commanded to accompany them to Metru Nui for labor or be killed. They were then rescued by Onua.

Geography
The ground screamed at every step and it constantly emitted heat greater then that of the Great Furnace of Metru Nui. Other land features included volcanoes that spewed burning ice, and waterfalls that were made out of dust rather than water. Additionally, if a Matoran was too lazy and sat down, the rock which the Matoran sat upon would turn the Matoran into a statue.

The realm was once accessible by boat or airship. However, the waterways later dried up and could only be reached through an overland path infested by Manas.

Trivia

 * Karzahni is the supposed 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 unleashed a Nova Blast, completely destroying the realm.
 * As part of the Great Spirit Robot's anatomy, Karzahni was located within its neck.
