A Spirit Star was a star that represented the spirit of a Toa. As long as the star burned in the sky, the Toa it represented was alive. A Spirit Star would correspond to the color of its Toa's Element (i.e. brown star for a Toa of Stone). Only Toa who accomplished a great deed could gain a Spirit Star, although this was not always the case. After the Toa Metru united together to defeat MakutaTeridax, Toa MangaiLhikan's Spirit Star split into six others, each representing one of the Toa Metru in the Metru Nui sky. On the island of Mata Nui, six particular stars were believed to represent the Toa Mata. Shortly before the appearance of the Seventh Toa, a seventh Spirit Star appeared alongside the Toa Mata's Stars. The Toa Inika generated their Spirit Stars immediately after their collective transformation. These Stars also orbited outside the Matoran Universe, circling around the Red Star above Voya Nui.
