You reap what you sow. Lead by Reaper, the Sin Eaters will continue to exact their vigilante justice on anyone who is part of or supporting the Federal States. They have angels everywhere, including the Republic. One of those angels brings news of the worst atrocity against fellow Americans committed by the Feds to Reaper. Every able-bodied Sin Eater rallies together to consume the sin. Can Reaper save what little is left of his humanity?
Meanwhile, the Republic is taking advantage of the opportunities afforded them by the Sin Eaters to advance against the Federal States. With the Republic on one side and the Sin Eaters where they are least expected the Feds are getting a run for their money. As always with the Feds, not everything is as it seems. Will the Republic be able to continue its momentum?
