Bara Magna

Bara Magna was a planet in the BIONICLE Solar System.

History
Bara Magna existed over 100,000 years ago when it harbored an advanced civilization of Agori tribes. The planet predated the existence of the Matoran Universe, whose Matoran and Toa inhabitants were designed by the Great Beings using the inhabitants of Bara Magna as inspiration.

At that time, it was afflicted by a world-wide disaster that transformed it into a desert world. The advanced civilization of Bara Magna was reduced to ruins scavenged by Tarduk and Berix, and the Agori were forced to use these ruins as they were unable to manufacture new technology and thus became less advanced. From then on, the Agori and a yet-unknown species of the Sand Tribe regressed into beasts of savagery.

Society & Inhabitants
Bara Magna was inhabited by several sapient species including the Agori, the Glatorian, the Skrall, the Bone Hunters, and the Vorox. Bara Magna was also inhabited by dangerous creatures, typically living in desert regions, and other animals used as transports, including the Sand Stalkers and Rock Steeds.

There was a social system on Bara Magna formed by the Agori following the disaster. In order to prevent a conflict over the scarce natural resources, two tribes would instead organize an arena match between two Glatorian, each on the behalf of a tribe. These two would duel, and the winning tribe would gain the resource.

Topography & Location
Bara Magna was located in space.

Bara Magna had a river after the disaster (and more than one before it), but never had any oceans. There were small regions on the planet that were not desert, but the vast majority of the planet's surface was a large desert peppered with oases. There were six cities on Bara Magna, all inhabited by a tribe of Agori except for one which was free for Agori of any tribe to inhabit. The cities are as follows:
 * Vulcanus, city of the Fire Tribe, led by Raanu. It is located by the Iron Canyon.
 * Roxtus, city of the Rock Tribe in the north, led by Tuma. It is located by the Black Spike Mountains.
 * Iconox, a city of the Ice Tribe; the leader is unknown. It is located in the White Quartz Mountains.
 * Tajun, a city of the Water Tribe; the leader is unknown.
 * Tesara, a city of the Jungle Tribe; the leader is unknown.
 * Atero Arena, the free city that Agori of all tribes except for the Rock Tribe could inhabit.

Notable plants were the Thornax that grew in the deserts, spiky fruit that could explode. Glatorian used these with Thornax Launchers in battle; Tuma and Fero also carried Thornax Launchers. Greg Farshtey has said that Teridax would not bother conquering Bara Magna, since it has relatively little worth conquering.
