Centaur

Wilderness Nomads Centaurs live in nomadic tribes. They roam in climates that they are able to survive wearing furs or hide. Hunter-gatherers by nature, they rarely spend extended periods of time in any one location. The tribes most often sleep under the stars or in cover of trees. They rarely construct anything more than a shield from inclement weather.
The migration pattern of a centaur tribe can be so large and so long that each generation may only see a location once in their lifetime. The tribe tends to follow the same migration through generations, setting and following a tradition. The long periods of time centaurs take to return to a location oftentimes leads to strife with civilizations that have sprung up on their path.
Reluctant Settlers The nomadic nature of the centaur tribes means that if you are unable to keep up due to age or injury, you are often left behind. Tribeless centaurs often assimilate into nearby civilizations in order to survive. The knowledge of the land offered by centaurs has made them valued members of the few frontier settlements they've joined.
Centaur tribes often have established trade relationships with the elves along their nomadic path. They've also been known to trade with other nomadic peoples or caravans if they are able to successfully communicate with them. Dealing only with elves for generations, most centaur have never bothered to learn the Common tongue.
