This story serves as the final chapter of Negan's life. It is not a story of victory or triumph but how he was shamelessly hounded and ended. As with almost every story there are two sides to it. We don't yet know where the other side of this story lead, if they celebrated their victory or they hung their heads in shame, if there was ever justice, or if there ever could be.
Negan was an NPC in a Pathfinder game, set on Golarion, his involvement in our story seems completely random and inconsequential. He is an inhabitant of a small shack at the edge of the Mindspin Mountains in Varisia.
Consider yourself warned if you read on, this is not a happy tale.
