Bio:
Karzahni was the tyrannical ruler of a hellish domain where Matoran who worked poorly were sent.[17] According to ancient legend, Matoran once labored in darkness, but those who excelled at their tasks were sent to Artakha where they would work in the light.[18] Matoran who were damaged or poor workers were sent to the realm of Karzahni, whose Kanohi mask had the power to make the victim see an alternate future, usually a frightening one.[1] There they would be fixed, but Karzahni did not do his job well and racked with guilt, equipped the "repaired" Matoran with weapons and shipped them off to remote areas of the Southern Continent instead of their homelands. After a while, Karzahni convinced himself that the Matoran were sent to his realm to be punished and trapped the remaining Matoran (and any new ones that came) in his realm. When the Turaga of many years ago realized that the Matoran were not coming back, they stopped sending them.
