Dume

Dume is the wise elder of Metru Nui and a former Toa of Fire, Dume has led Metru Nui for roughly fifteen thousand years. In the time leading up to the Great Cataclysm, Dume was abducted and secretly replaced by Makuta, who took on Dume's appearance to fulfill his sinister goals. Turaga Dume was imprisoned in a container beneath Po-Metru. He was awakened and freed sometime during the Visorak's conquest of the city (that story has not yet been told). In the thousand years while the Matoran were on Mata Nui, Dume and the Rahaga fixed what damage to the city that they could, and Dume also studied the stars. When the Matoran returned to Metru Nui, he told the Toa Nuva what he discovered the stars were saying: that Mata Nui was not only sleeping, but dying. He sent them to Voya Nui, where they could find a Mask of Life that could save him; but decided not to tell the Matoran of his discovery to save them from worry - a decision that led Jaller to declare a citywide strike because he was tired of the Turaga secrets. Dume wears the Kanohi Kiril, the Noble Mask of Regeneration, which allows him to repair inanimate objects and buildings, but not heal living things. He carries no specific "tools".
