Origin is the original homeworld of the Flowers. Orbiting around a black hole, it was seeded by a plothole from Earth with a range of plants. When Origin's sun was consumed by the black hole, a radiation burst transformed these into the sentient Flowers known today, with the Sunflower Official being the first of the Firstborn.
It was on this world that the Organisation was founded, and on which the Civil War took place. The planet was later destroyed during the Cascade due to the rapid proliferation of the plothole network undermining its structural integrity.
