The Traveler is very similar to the Explorer, but is not expected to fight or make his/her way through unknown wilderness. The Traveler focuses on peaceful skills, society, and obtaining a working knowledge of the civilized geography of his or her world.
Any class can be a Traveler, as few skills normally associated with classes affect the success of the Traveler. Helpful attributes could include mounts, flying, teleportation. The Traveler is expected to take photos, or screenshots, or even create sketches of the places visited. Field guides or general notebooks should be created as well.
