After the horrifying events that occurred at the ending of Golden Son, Darrow has now been at the mercy of the Jackal the past year. The Reaper is now barely a shadow of himself, as he struggles to get through each day in the never ending darkness.
Under the surface of Mars, a young Red, Darrow works in the mines. The lowest cast, the Reds are mining helium-3, as they believe they are making the surface of Mars habitable. The world of men is divided in a strict hierarchy that has placed Darrow and his fellow Reds at the bottom. At the other end, are the Golds - almost godlike figures that make the stronger and better cast, they rule society through fear and intimidation.
