I've been working on the idea of The Hexarc for several years, but never really explained it.
This is the philosophy started by Mata-Nui and his elemental council on the Holy Island of Korrothis in the early years of the Matoran Universe. The elements can be expressed as a wheel with six spokes, with one half in light and the other in shadow. Light and Shadow are opposites. The prime arcs of; Air and Earth, Fire and Ice, Stone and Water are also seen as opposites. These opposites balance each other out, and it is the Duty of all Mata-Nui’s faithful to do what they must to make sure the elements stay in balance.
