A UNSC ship makes the discovery of a lifetime. A planet, whose occupants are human and humanoids living together on the surface in an Medieval-Era. Forerunner ruins dot the land, engrained into the culture of the people. The ships in orbit are attacked however and although they win the battle they are forced to fall back. The survivors of the battle are stranded until their return.

David is an ONI Spartan, a cold killer. He meets Claire, a soldier who shows him a life beyond the pain. Now, to save everything he wants, he must fight everything he knew, and decide what price he must pay for his humanity- and his love.

In 2549, the Covenant attacked the colony Tulane. PFC Sylvester Bishop was stationed at outpost Bravo Orca Six Sierra, along with the rest of November Company. This is the story of their doomed resistance.

The war has been over for nearly a year, but the Covenant are still a threat, humanity and the Sangheili find themselves beleaguered to keep the peace, and dangerous secrets infest everything they do. In order to stand a chance of turning the tide, a prototype squad comprised of the best soldiers both races have to offer is put into action.
