Saga Guides/The Bohrok-Kal Strike
After their Krana were removed, the Bohrok were reprogrammed to repair the damage that they had caused. The Toa were now stronger than ever before, now that they had been transformed into the Toa Nuva. The Bahrag were imprisoned and celebrations were in abundance. During the festivities, Hewkii found Pohatu's Nuva Symbol. At the same time, Tahu's Nuva Symbol had also appeared, and was inserted in a niche in Ta-Suva. Turaga Vakama then went into the Suva, explaining to Tahu about the Kanohi Vahi, the Legendary Mask of Time. He finally gave it to the Toa Nuva of Fire but told him to use it only in an emergency. After checking up on their villages, the Toa met again. After a brief talk, they had a show of their newfound powers, battling each other with their powers. After that, they talked about splitting up. Despite Gali's warnings of past events, everyone went their separate ways.
The Bohrok-Kal, six elite Bohrok, awoke. Their only mission was to free the Bahrag, but they did not know where or how to find them. Because of this, the Bohrok-Kal began to journey around the island searching for any possible areas where the Bahrag could have been imprisoned, and in the process, found out that they needed the Nuva Symbols to free the Bahrag. The symbols acted as a key to the cage. The theft of these symbols would take away the Toa Nuva's elemental powers. That day, Lewa's Nuva Symbol appeared in Le-Suva. He then tried to show the Le-Matoran his flying powers, but plummeted due to the theft of his Nuva Symbol by Gahlok-Kal, and thus his elemental powers were lost. Fortunately, Kongu and Ka saved Lewa in freefall.
Kopaka's Nuva Symbol is received in Ko-Koro. At Ko-Koro, Kopaka's Nuva Symbol also appeared. Matoro promised to guard it for him. Later, he was walking around Ko-Wahi, troubled by the separation of the Toa Nuva. Kopaka wondered if someone planned for this to happen. As he was walking over an ice bridge, his elemental powers were lost, as Nuhvok-Kal had stolen his Nuva Symbol. Despite Matoro's efforts at stopping the Bohrok-Kal, Nuhvok-Kal easily defeated him by increasing his gravity to the point that he could not stand up. Kopaka started to fall into the chasm below, but he managed to save himself by catching the side of the chasm with his tools. With the help of Turaga Nuju, who appeared on the scene, Kopaka was able to make it out of the chasm. Jaller and Takua were journeying to the village of Ta-Koro. Along the way, Jaller heard a noise and readied his disk. However, the source of the noise was from Puku, who had followed Takua. The two Matoran and the Ussal continued on their way to village of fire. Once in Ta-Koro, Jaller and Takua went to report to Vakama about the Bohrok War. Upon leaving Vakama's hut, they saw one of the guards trapped in a field of electricity and a creature that looked like a Bohrok taking Tahu's Nuva Symbol from the Suva.
