Part 4 of the epic post-apocalyptic adventure Fallen sends you on a quest. The group is now exposed, vulnerable, and in need of a power source. If they expect any chance of survival in this changed world, they need to retrieve a piece of technology hidden in the desert. Dursky decides that taking the group on his quest will only put them all in danger and slow him down. While they are sleeping one night he begins his journey. After hearing stories about the final Guardian and what he has been up to over the last four years, Dursky treads with caution. He meets new allies, enemies, and a few that remain undecided. Even without the group Dursky quickly realizes, this may not be as simple as he thought.
