Eastern Chain

The Eastern Chain of the Southern Islands is one the two chains of many domes within the Matoran Universe located within the left leg of the Great Spirit Mata Nui and was the former Kingdom of Barraki Takadox. Amongst others, the domes of Ackro Nui, Be'nau, Fasha Nui, Keetongu, and Mashau Nui are housed therein.

History
The Southern Islands were created by the Great Beings during the construction of the Matoran Universe. The islands became the home to several species but exploration and settlement by the Matoran took much longer than most parts of the universe. One of the islands contains a pool of green and black energy, where the Great Spirit Mata Nui created the Makuta species. The island was eventually populated by Matoran, who were later driven out by Rahkshi acting on the order of the Brotherhood of Makuta, who turned the island into a staging area for an assault on the Southern Continent. Two members of the Order of Mata Nui, Axonn and Brutaka, later arrived on the island to destroy the pool, bringing along the amassed armies of the Skakdi warlords from Zakaz to combat the Brotherhood's forces. During the reign of the League of Six Kingdoms, the Barraki did not capture many of the islands, due to the fact that they were strategically worthless. Pridak did make a point to take over the home island of Botar and his species. Botar's replacement in the Order of Mata Nui also came from this island. After the Matoran Civil War, Makuta Chirox was assigned to oversee an island in the Eastern Chain, but he abandoned this position in favor of a different location in the Eastern Islands. Some of the islands were also conquered by the Visorak at some point in time and at least one island was liberated by Toa Lesovikk while he was exploring the area. The northernmost island of the Eastern Chain, located within the Dome of Mashau Nui, is inhabited by numerous Rahi mutated by the Energized Protodermis Entity. On the island is a large lake of Energized Protodermis that lies inside a large cavern. One of the islands in the Eastern Chain is the homelands of both the Tahtorak and Keetongu's species located within the Dome of Keetongu. Here, Keetongu's species used Tahtorak as mounts before they were wiped out by the Visorak. Keetongu himself escaped to the Island City of Metru Nui. Following a confrontation with Teridax after the Makuta had taken over the body of the Great Spirit, Teridax teleported Axonn, Brutaka and Keetongu to somewhere within the Southern Islands.

Landscape
Due to the various amounts of islands, the landscape of the chain varies from location to location. They are generally barren, with few amounts of species living on any given island.
