Conference tells the story of the first meeting of all 12 Walkers at the ExoGen conference. It is told from the perspective of Sally, a human girl who attended Magna College during Mendax City, but through Joshua's early attempts at time travel, she was thrust into the Tribus age. Sally's flashbacks to her time in Tribus reveal new details about the Walker's personalities, and of Sally's involvement in awakening Holly from the ocean.
