Ancestors

Long before the arrival of the Flood to the Milky Way galaxy, humanity, who at the time was still composed of many different species, had achieved a considerable level of technological sophistication, achieving interstellar travel and colonizing planets along the Orion Arm, then a minor sector of the Forerunner's domains. After forty thousand years of expansion, the collective human genus waged war with the biologically-similar Forerunner species. They were crushed by the Forerunner war machine. As punishment, humanity was reduced to a pre-technological state and exiled to their homeworld, Erde-Tyrene, overseen by The Librarian.

Forced to start again, the collective human genera would try in vain to rebuild their former glory, establishing wooden cities and steam-powered waterborne vessels, though even these efforts would not be enough to halt their technological and cultural collapse to the Tier 7 tribes encountered by the Forerunners during the construction of the Ark portal in east Africa.
