The chosen matoran followed a map wrapped around the stone to the Toa temple. There they placed the stones in the table at the middle of the temple and with a string of light each of the matoran transformed into 6 new mighty toa warriors each sworn to protect the heart of Metru Nui however they were unsure what it was. Legend said that there were 6 special disks, one from each Metru, so the Toa decided that they each would go after the disk from their home Metru, and so the great toa started the biggest scavenger hunt ever until all six of the disks had been found. The Toa went to the caladium to reveal the disks to the leader Turaga Dume. The Turaga was impressed, but insisted that they could not prove themselves with gifts but with deeds. So they had to face the sea of protodermis, the toa survived but then a swirling wind raged above a hole and Vahki enforcers came to seize the Toa, 3 of the toa survived the others falling into the hole. Vakama and the other two toa who escaped thought the Turaga Dume may have been evil but will they be right? Will they discover the heart of Metru Nui? And most of all will they save Metru Nui?
