The torch is ready. Plant it at the end of the dock and be prepared to face whatever comes forth.$B$BI have no idea what the torch's smoke may reveal... if anything emerges at all. I must say, I have my doubts about this kind of folk magic, but we haven't time for anything else. For your sake and Jarl's, I wish you luck.
Mordant Grimsby at Swamplight Manor wants you to plant the torch at the end of the dock and defeat anything that appears.
