Wool introduced the silo and its inhabitants. Shift told the story of their making. Dust will chronicle their undoing. Welcome to the underground.

Wool: What would you do if the world outside was deadly, and the air you breathed could kill? And you lived in a place where every birth required a death, and the choices you made could save lives—or destroy them? This is Jules’s story. This is the world of Wool.

Shift: What would you do if you were forced to survive when everyone you cared about was dead? And the only place you could live was in a closed-off world buried deep below ground? This is the start of the silo. This is Shift.

Dust: What would you do if the fate of everyone you know rested in your hands? And the choices you make could lead to their salvation, or be the death of us all? This is how the story ends. This is the return to Dust.
