Mason Harn
From Witcher Wiki
Harn is the village mason with not the best reputation. Geralt meets him one day while strolling the area near the village of Murky Waters. He's having a great deal of difficulty repairing the bridge. He and his son, Pat, work on it all day, every day, but each night the Griggs undo all their hard work. What to do?
He says that he's been having dreams in which ghosts who haunt the bridge have asked him to rebuild it. Since it has fallen into disrepair, they cannot rest.
