Spirit of the Ancient Traveler is an unused undead Nord in The Elder Scrolls V: Skyrim. Oddly, he does not have a head, making him one of only two ghosts in the game without one, the other being the Headless Horseman.
Spirit of the Ancient Traveler does not appear in-game and can only be located through the use of console commands. However, at the location Wayward Pass, a strange skull named, "Ancient Traveler's Skull" can be found. It is possible that the character was supposed to appear in this location, but the encounter was cut from the game.
