For all the great heights humanity achieved, it couldn’t save itself in the end. After being the only survivor of an incident that wiped out his family and friends (all his fault), Enos wondered whether his golem companion, Hallie, was right that there was really a reserve of human essence hidden somewhere, waiting to be found. (What if he couldn’t save humanity?)

Someone also could be still alive out there. (Nope) And he had to save them first. (There was no one to save.) These (pointless) detours led him to a mysterious being, and his journey to (fail to) revive the human race was about to start.
