|Residents||Ta-Matoran, Toa Tahu, Turaga Vakama (all formerly)|
When the Toa Metru first came to the island, Vakama personally chose Ta-Koro's location, keeping a good defense in mind. After the Toa returned with the rescued Matoran, the village was constructed using parts from some of the Matoran Spheres and the Airships, while the living structures for the Ta-Matoran were built from hardened lava.
After the village was constructed, Makuta Teridax's promised year of peace expired, the Great War broke out between the Makuta's infected Rahi and the Ta-Matoran. In one battle, Ta-Koro shrank when the Charred Jungle was taken by the Rahi. However, the Makuta was temporarily defeated by the Toa Mata, and peace was restored to the village for a short time.
During the Bohrok Invasion, a swarm of Pahrak and Kohrak attacked Ta-Koro in an attempt to "clean" the area. Kapura managed to slip away to Kini-Nui to warn the Toa Mata of the attack. The Toa used the Kakama power of their Golden Kanohi to speed to the village and put a stop to the oncoming swarm. Once the Bahrag were defeated, Ta-Koro, along with the rest of Mata Nui, was rebuilt.
Shortly after the Mask of Light was found by Takua, Teridax unleashed three Rahkshi to acquire it. The Panrahk, Guurahk, and Lerahk then proceeded to destroy Ta-Koro in their search for the mask, although the Matoran evacuated before the village sank into the lava.
Ta-Koro was located in the middle of the Lake of Fire. Vakama designed it to resemble a fortress to help the Matoran defend themselves. Ta-Koro was connected to Ta-Wahi Beach and the Charred Forest by a stone bridge which could be lowered into the lava when necessary. Ta-Koro was also the location of several lava farms and a Kolhii Field constructed following the Bohrok-Kal Strike. Ta-Koro was later destroyed by the Rahkshi and sank into the lava that surrounded it. Though the Kanohi Masks of Tahu were destroyed, Tahu's Nuva Symbol was brought with the evacuated Matoran, preserving his power.
The Ta-Matoran were the primary Matoran residents of Ta-Koro. The Matoran of Ta-Koro resided in homes made from cooled lava, and they performed day-to-day activities such as Lava Farming or Lava Surfing. Several notable Matoran lived here, such as the Captain of the Guard, Jaller (now Toa Mahri of Fire), and the Chronicler, Takua (now Takanuva, Toa of Light). The Ta-Matoran's resistance to heat was what enabled them to live comfortably here.
