Precursors

Precursors were the first race to achieve space-faring technology in the known universe. They originated from the Flood Galaxy billions of years before the League was even establised. Like the Forerunners that succeeded them, the Precursors decided that they were responsible for taking care of everything in the Galaxy but they soon realised that, no matter how hard you try, there will always be conflict, strife, famine, pain, disease and death.

They therefore decided to adapt and assimilate everything in the universe into their collective, meaning there will be no hardships and everyone will think and work together, solely for the advancement of the species. They adapted, changing their DNA structure and fusing themselves together to form Gravespeare, and he in turn created the Precursors gift to the Galaxy, the ultimate species, the cleansing flame that will burn away strife, pain, disease, famine, crime and hate. This species was... The Flood.
