The K'Chain Nah'Ruk, for example, the Soldier of Death who sets up the premise for Orb Sceptre Throne, and a few others. There may be occasional roughness in how some of the action unfolds, but the more I re-read, the more convinced I become that Erikson and Esslemont plotted out quite a bit of the overall story years before they began writing their novels. I even saw a reference at the end of HoC to Lieutenant Ash, who appeared in NoK.
