Sobek

History
The planet Sobek has very little liquid water. The entire planet is covered in a vast tundra, and the people of Sobek live near the poles in order to melt the frozen water to have something to drink.

Despite a small contingency of ore, Sobek has had very little to offer in the way of resources, and because of this has been left alone by every major power in the galaxy for the last several thousand years. In this isolation, Sobek has developed a rich and unique culture among the nomadic people that live on the planet. One of the most famous rituals, the Rite of Becoming, asks newly matured teenagers to gather the prickly fruit that only grows in the "temperate" latitudes some several hundred miles from the ice tribes of the poles and bring them back so they can use its juice to paint blue-green patterns on their bodies. Sobek has a deeply enshrined way of living. The people of Sobek do not even follow the Way of the Matron. They follow their own many gods that they see in the dust clouds or in the fires that melt their water.

During the War
Although there was not much chance the Overlords would decide to attack Sobek, the tribes decided that it was better to be cautious, and so asked the Extran Syndicate to agree to protect them. Too busy trying to free their home of Sekhmet and not trying to get more involved in the war, the Extran Syndicate politely declined, saying the Overlords we're unlikely to attack anyways Sobek anyways. When The Collective made itself known at the battle of Osiris, some leaders first proposed perhaps asking The Collective for help, but the unholy hybrid of man and machine made them nervous, and they would not accept The Collective for another decade when the Overlords blockaded their trade route to Magna.

The Source
The Source was overjoyed to be able to learn from and fuse with a group of people so unique, with so much to offer, he sent his very best Cyborgs, dressed in traditional Sobek garb and with Sobek body paintings. But the people of Sobek found the things so horrifying they hunted them to extinction. Again, The Source tried win over the people of the planet, by sending mostly biological entities from Morpheus that brought with the most fantastical and awe-inspiring blends of biological and machine, to showcase what a life in The Collective had to offer. Again, the people of Sobek refused to even speak the travelers, insisting that The Collective protect them from orbit. The Source was unhappy, and decided to break off a part of Origin itself (the first time it had ever done this since Osiris) to speak with Sobek directly.

When the large robotiod arrived, the people of Sobek stood speechless in fear, but defiant of anything The Source had to offer. They demanded that The Source leave them, they no longer wanted its protection. The Source could not do that, it had to be with them, and so landed on the planet, cyborgs with outstretched arms, ready to help the people of Sobek.

All the tribes in Sobek resisted passively, refusing to speak to the cyborgs, or even look them in the vision tubes. Standing, motionless, waiting for The Source to leave the planet. The Source was furious. Who were these people to refuse gifts they could not even comprehend?! If only they knew what they were missing... If only The Source could show them...

Very little is known about exactly what happened, by when The Source left the planet to return to Origin, no living biological organisms remained. The people of Sobek had resisted so vehemently their living forms could not be incorporated to The Collective. Even through violence, The Source could not force the people of Sobek to assimilate. Throughout the galaxy members of The Collective screamed and overheated and tore off their own limbs.

By the time The Source returned to Origin something had changed in The Collective. The Source shut itself in the core of the planet Origin and has never left, leaving The Collective to manage itself mostly cut off. Few have even heard from The Source except to confirm that integration is no longer possible. Sure, new planets have joined The Collective, even with cybernetic implants, but The Source has not fully integrated a consciousness since.
