Character Development
Sister to Mayor Thorin and owner of the only bar in Hambry, Coral is something of a gossip, and informs the Gunslingers of her brother’s intentions toward Susan Delgado not long after their arrival in town. She also begins an affair with Eldred Jonas, and in doing so shifts her loyalties toward the Big Coffin Hunters and away from her family and the people of Hambry. After the events of Reaping Night, and the battle between the Gunslingers and Jonas’ men, she joins forces with the Clay Reynolds and rides along with him until her death.
