Osiris

Osiris is the capitol planet of the The Collective, though not the homeworld of The Collective, as it originated at the planet Origin (or arguably Doom).

History
Before the Galactic Civil War, Osiris was a prospering trading outpost known for its shipping and logistical connection to The Outer Band planets. The oligarchy on Osiris had grown complacent and its people were passive and easily deceived, and so the Overlords were right to think the planet could be easily provoked into join them, that is until a previously hidden robot consciousness known as The Source intervened and saved the planet from subjugation.

After The Source's saved Osiris from destruction in 21319, the people of Osiris were so grateful to The Source for saving them, most asked to be joined into The Source's cyborg collective. This was the first joining of The Source's consciousness and biological consciousness that would eventually form The Collective.

Modern Osiris
To this day machine, hybrid, and biologic people live on Osiris in harmony, all ruled over by The Collective and The Source. While the biologics are not fully integrated into The Collective, they are allow full rights under its rule. This is contrasted with Origin where no biological being has ever been allowed step foot.

There are of course some biological organisms who resent The Collective's rule, but by and large Osiris represents the best The Collective has to offer- peace and harmony.
