Master Chief and the Order of the Phoenix by LordCaldrin45 reviews
It's been four years since Master Chief escaped the explosion of Halo. The wreckage of the Forward Unto Dawn went through a black hole, teleporting Master Chief and Cortana to back to 1995 Earth and crash land in England, where Harry Potter is taking his fifth year. A new adventure is about to begin. Review!
