Orentorus

Orentorus is a planet similar to Spherus Magna. A rogue group of Great Beings went there to re-create the events that happened on Spherus Magna.

History
Arrival of the Great Beings

At the Time that the Toa Mata became Toa Nuva, a rogue group of 6 Great Beings left Bara Magna in an attempt to find a similar planet, they did. It was on Orentorus that they decided they would carry out their experiments. They changed the planet to have similar properties to that of Spherus Magna and made a core of Energized Protodermis. Then they created the Elemental Lords, Agori, Skrall, Glatorian and other races of Spherus Magna.

Core War

The Great Beings made sure that the Core War would happen. It did and the tribes fought over the Energized Protodermis. The Iron Tribe, however, had managed to set up a mine and were trying to harvest the substance with little success. They machinery exploded. The explosion was amplified by the Energized Protodermis running beneath the planets surface and a third on the planet exploded. Unlike with Spherus Magna, no moons were formed. The entire third broke into small lumps of rock with no atmospheres. The entire Iron Tribe and Fire Tribe, along with part of the Jungle Tribe were killed.

Mata Nui 2

Continuing there research, the Great Beings created Protodermis, Matoran, Toa and Mata Nui 2 (amongst other beings). The majority of Beings from the Origional Mata Nui were recreated and placed inside, along with some new ones. Mata Nui then left, with a fault in his systems that even he couldn't detect. The fault was deliberate.

Orentorus-post shattering

After the war Glatoru=ian ruled over the Agori as war-lords. They fought amongst each other, the Agori forced to be soldiers. The only ones who opposed this were Gresh and Tarix who lived with Agori in a secret location. But they were not strong enough to fight the other Glatorian.

Lights out

Years later, when Mata Nui 2 had returned and was nearing Orentorus, the fault kicked in and he fell into a coma. He is now in a decaying orbit around the planet. When this happened all lights generated by him in the universe went out, causing eternal night.

Within him the Great Beings had placed many dangers including The Wraith, The Rahkshi Legion and the Madness plague. These are all things the inhabitants of the universe will have to over come. The Great Beings placed dangers on Orentorus as well. They did all this to study the reactions of sentient beings. Why they did this is unknown.

Differences to Spherus Magna

 * No Annona
 * One third of the planet broke away

These are a few of the more important differences but are not all of them.
