(PRESTIGE CLASS)
Those whose wanderlust drives them to push the boundary of safe environments sometimes seek the calling of the horizon walker. Horizon walkers are masters of travel, always seeking to find the safe ways through inhospitable terrain. They are comfortable in places others speak of only in hushed whispers, and they can both venture forth onto untrod paths themselves and guide the less-traveled through such hazardous lands.

Though rangers are most likely to be attracted to the ever-wandering life common to horizon walkers, barbarians, fighters, and rogues have also been known to find it appealing. Horizon walkers are most common in areas on the edge of civilization, where they can easily spend time away from the known and boring streets of settled lands.
