Rosselin is an Orlesian corporal.
Rosselin can be found at the Western Ramparts in the Exalted Plains, fighting undead. The dead bodies piled into pits are attracting spirits and causing the undead to rise. Rosselin and his soldiers have been trying for weeks to retake the western and eastern ramparts outside Fort Revasan from the undead, but with no success. With the Inquisitor's aid, Rosselin finally succeeds in his mission. With the ramparts secure, the Imperial Army is once again able to patrol the plains hunting down demons and the Freemen of the Dales (deserters who have been attacking travelers), while they wait for the outcome of the peace talks at the Winter Palace in Halamshiral.
