Slickrock is the name of a battle between Highprince Nalanar and Dalinar's forces.
Geved fought in Nalanar's second infantry and survived. He reminisces with Dalinar when they meet in the aftermath of the Battle of Vedenar. Dalinar concedes that Nalanar nearly beat him at three different points during the battle. The discussion acts as a counterpoint to Geved's experiences during the Battle of Vedenar, talking about the effects of the Thrill.[1]
