Rolf was a recruit of the Night's Watch stationed at Castle Black. Rolf was killed by Wildlings, north of the Wall
Rolf is caught discussing his recent trip to Mole's Town by the Lord Commander, Rheagar II Targaryen.
Rolf, Beric Storm, Artos Harclay, and Gawen go on a ranging mission north of the wall. They encounter a band of five wildlings. Beric commands the rangers to ambush the party after getting no information from scouting the group. Rolf dies in the fight, something that weighs heavily on Beric who blames himself for Rolf's death.
