He was set adrift, along with Cortana, after the events of Halo 3 and spent four years in a cryogenic freeze. After his ship comes across Requiem, Cortana wakes him with a desperate cry for help. The planet was purposefully built by the Forerunners to act as a bomb shelter for when the halo arrays went off…and it worked. As a result, the planet is home to an army of Promethean super soldiers who are rather protective of their world. Bad news for our hero."
