Orcs are a race of mountain dwelling humanoids. They are well known as bloodthirsty raiders. They however have a very intricate culture with a very strict codified feudal caste system. Each orcish tribe is has a chieftain whom has a number of feudal lords under him, who in turn have a large number of peons and slaves. Different tribes constantly war with each other over ancient differences. But even the inter tribal warfare is highly codified but their code of “honorable” combat. These code do not apply to outsider however, as they are not worthy of honor.
Every few decades a charismatic chieftain rises to power and unites multiple tribes forming a horde that comes out of the mountains sweeping through the countryside. Eventually the infighting between the tribes causes the horde to fall apart. But in past hundred years Hok’tar the Eyeless managed to unite many tribes and hold them together, creating Shattered Sword Territories.
