One hundred thousand years ago, the galaxy was populated by a great variety of beings. But one species – eons beyond all others in both technology and knowledge – achieved dominance.

They ruled in peace but met opposition with quick and brutal effectiveness. They were the Forerunners – the keepers of the Mantle of Responsibility, the next stage of life in the Universe’s Living Time.

And then they vanished.

This is their story.
