Citra and Rowan have sunk to the bottom of the ocean, along with the rest of Endura. Now, Goddard is in control of a better part of the world and is changing scythes rules on gleaning so they are more relaxed. The Thunderhead has deemed all of humanity unsavory, except for Greyson, who has become an icon for the Tonists.
After becoming a scythe, Citra tries to stop the growing corruption of the scythdom from within, while Rowan has become the infamous Scythe Lucifer after being denied his scythe ring. He has been finding corrupt scythes and killing them - truly killing them - and the Thunderhead has done nothing to stop him.
