Nicholas the Traveler is a man who travels all over Tyria, handing out suspicious items to adventurers that are bold enough to collect the various items that he requests. After all, he never tells you what's in those items that he gives, when he receives his requests. His location and the requested item changes every week on Mondays at 15:00 UTC and this is apparently due to the fact that he has nothing else to do with his life.
