Cerinrim

The Cerinrim are the most blood thirsty and warlike of the tribes of Far Harad

History
The vicous Cerinrim roam the Bushlands of Far Harad. Early in their history the resembled the Moredain in many ways. It changed when a powerful cult seized control over several tribes and declared war on the others. The Cultist conquered the bushlands  and soon all of the Cerinrim worshipped the war god. The Cerinrim began to raid the Moredain, war was a way of life. They became brutal and savage warriors prisoners were ritually sacrificed to the war god. The greatest honor a Cerinrim could have is to sacrifice a Half-Troll to the war god. They have declared Sauron a false good and wage war on his followers.
