Master Luther:
Did you come for the Mark of the Searcher? The Mark is given to those who's ability for 'finding hidden things' is recognized. Every year, numerous Hunters, Scouts, Excavators and even some Assassins come to me in hope of receiving the Test of the Searcher though you don't seem like one of them... Are you sure I am the right person you are looking for?
(Quest only available for Rogue, Scout, Assassin, or Scavenger above level 39.)
