Artakha was a figure of legend. It was said that he had never been seen in all the time he reigned on Artakha. Matoran mythology included stories that Artakha was a Great Being or that he was Mata Nui himself, although none of these were true. Artakha had great talent as a designer and builder. The modern look of cities in the Matoran universe was credited to his influence. According to legend, those who wished the impossible built could leave raw materials at the gate of Artakha's fortress and return in the morning to find the item they desired. A persistent myth was that Artakha wore a Kanohi Mask of Creation.
