Back when the planet Bara Magna was created, the Great Beings brought the great spirit Tera Nui to the planet to be their protector and foresee all of Bara Magna. However, the Skrall believed that Tera Nui was merely a barricade for their mission of planetary conquest and an elite class of Skrall, led by Tuma, rebelled against him, sending him into an unending sleep and the Agori civilization that flooded through Tera Nui (called the Agori Universe) vanquished. The great spirit's body was then remade into the Black Spike Mountains, where the Rock Tribe reides.
