A great explorator fleet sets out into uncharted space, the Halo Worlds at the galaxy's edge. The armada contains contingents from every aspect of the Imperium, from the humble troops of the Astra Militarum to the mighty Space Marines – all led by the ancient tech-scholars of the Martian priesthood. They seek an ancient and priceless technology from the birth of history, but what they find is more powerful and deadly than any of them could have imagined.
