As the Matoran of the island of Mata Nui prepare to return to their ancient home of Metru Nui, Turaga Vakama begins to tell the tales of its fall a thousand years ago...

The city of Metru Nui, long peaceful under the reign of Turaga Dume, was under attack. For the past month, a vicious plant called the Morbuzakh had been terrorizing the edges of town, destroying buildings and making Matoran vanish without a trace. The enforcers of order, the Vahki, could do little to stop the spread of the Morbuzakh, and the Toa who guarded the city had gone on missions from which they never returned. Only Toa Lhikan was left, and when he saw two Dark Hunters in the city - a familiar being named Nidhiki and his partner Krekka - he became extremely worried.

Lhikan decided to break into the Great Temple and steal six Toa stones, which he charged with his own Toa power. He then set about delivering the stones to Matoran that he had carefully chosen: teacher Nokama, transport driver Matau, carver Onewa, archivist Whenua, and scholar Nuju. He had just delivered the last stone to the final Matoran, a maskmaker named Vakama, when the Dark Hunters caught up with him. In order to save Vakama from the Hunters' attack, Lhikan allowed himself to be captured, but not before telling the Ta-Matoran to "save the heart of Metru Nui".
