They come from the direction of their name the desert places near the sea of Rhun,
east of Mordor. They are also tribal and descend from the men who refused to
join the Elves during the second Age, they have a strong caste system that
distinguishes between the warriors, servants and workers who looked over them.
Strong tribes often subjugated weak ones and they often went on raiding parties
to capture men and women as slaves. They often paid tribute to Sauron and gave
up their army to his needs, they are highly disciplined troops and effective
against all enemies, being from such a proud and conquering race. On the fields
of Pelennor they are sent after the great trolls to take over the city (fingers
crossed this is in the SE) but soon after that defeat and their alley Sauron is
destroyed, Aragorn leads
the people of Gondor against them causing them to retreat further and further
into the East, out of the reach of Gondor. The conquers have become conquered.
Their sleek pointed plate armour
and winged helmets give the Easterlings a menacing look and along with their
crocked swords and sharp spears they are a worthy foe.
