Karzahni

Karzahni is a name applied to multiple things in LEGO fictional Bionicle storyline, all of which represent death and suffering:


 * An ancient ruler; legends state that poor workers were sent to him to be punished.
 * The underworld-like domain where the aforementioned ruler reigns.
 * A plant monster created to terrorize the city of Metru Nui. It was named "Karzahni" after the legends of the ruler.

Most Matoran only know of the ruler and his realm through legends (the plant is unknown for the most part, though the Matoran of Metru Nui know of it through their Turagas' stories). Given the widespread nature of these legends, Karzahni is a common figure in exaggerated "boogeyman" horror stories. Angry Matoran also occasionally shout at each other to "Go to Karzahni!" (a direct reference of a human expression concerning hell, though possibly a little less profane considering how flippantly the Matoran refer to the ruler).

The Ancient Being
Karzahni and his brother Artakha were two of the first creations of the Great Beings, and each was given a domain to rule over. Originally, Matoran were sent to Karzahni in order to be repaired and returned to their homelands - but Karzahni never really knew how to do his job. Instead of rebuilding them to restore their efficiency, Karzahni's attempts severely shortened their stature and strength. Ashamed to let others see his work, he sent a number of "repaired" Matoran, with weapons to compensate for their physical shortcomings to Mount Valmai, far away from everyone. After several more failures, Karzahni became convinced he was not to blame, but the Matoran themselves. They should be punished instead being fixed so he imprisoned the Matoran. When nobody ever returned from Karzahni, Matoran eventually stopped being sent to him. Over time, his and Artakha's realms passed into legend, with the myths saying that bad or lazy Matoran were sent to him not for repair, but for punishment. That's how the phrase "Go to Karzahni" came to be in arguments.

When Matoran enter Karzahni's domain, he has them abandon their old masks as a way of making them abandon their old identities, and he uses his mask to show them terrible "what-ifs", making them lose all hope. For instance, Jaller saw the devastation which would have come to pass if Takua had never become Toa Takanuva.

Until recently, Karzahni did not even know of Makuta, Mata Nui, the Toa or anything else of the world outside his kingdom. His first knowledge of them came from the Matoran who later became the Toa Inika. At first, he didn't believe the tales they told, but then through his own mask power he saw that the universe would cease to be if Mata Nui died. Now that he knows what exists outside his kingdom, he aims to take control before Mata Nui wakes up - and it seems that Makuta will become one of his first targets.

Karzahni has an ancient appearance, with ebon- and gold-colored bladed armor and a mask that is seemingly made of three or four older masks patched together. This Kanohi Mask can make himself and others experience alternate or possible futures; usually bad ones. He also carries a burning chain and his gauntlets crackle with energy.



The Plant
When plotting his scheme to take over Metru Nui, Makuta designed an intelligent plant creature to drive the Matoran towards the city's center; he named this creature "Karzahni" after the fabled tyrant. However, the Karzahni was too powerful and too ambitious, so Makuta abandoned it and instead engineered a weaker plant creature, the Morbuzakh. Karzahni swore revenge on Makuta, but this was taken from it when the Toa Metru imprisoned Makuta during the Great Cataclysm.



When the Toa Metru were returning to the city, Toa Nokama was critically injured by the Rahi Nui and Karzahni took the opportunity to strike a deal with the Toa: it would cure Nokama if the Toa would get him some energized protodermis. They did so, and Toa Nuju figured out that the Karzahni not only wanted the protodermis to become more powerful, but to save its life; as Makuta deliberately designs a fatal flaw in all his creations. However, the Karzahni was not destined to be transformed by the protodermis, so it was instead destroyed, leaving nothing but dead wood.

Shortly afterward, the Toa Metru used the dead Karzahni branches as part of a boat to bring them to Metru Nui; but none noticed a single sprig that seemed to have sprouted when immersed in the water. This sprig later grew into a new Karzahni plant, with all the memory and experience of the old. This Karzahni hid for a while, and when the now-free Makuta sought the Vahi Mask of Time, he made a deal with Karzahni and had it impersonate the Morbuzakh in an illusion he crafted for Toa Vakama. But after the illusion had been shattered, Karzahni switched sides and helped Vakama by bolstering his self-confidence, revealing that despite evidence that he and his team had found, they were always the ones destined to be Toa. It also said that it had gotten this information from a member of the Order of Mata Nui (and implied that it killed the member). By this time, Makuta had caught up with the two, and Karzahni was seemingly killed again when Makuta encased it in a shell, cutting it off from heat and light.

The Karzahni had full control over its vines and branches, and was able to produce healing sap and fruits at will. It communicated using telepathy and was able to gather information through any of its growth.
