Excerpts taken from World of Thedas Volume 1 where the word Kossith is extensively used to refer to the race.
"There was a time when the kossith race prayed to animist gods.
They were wild then, devot ed to a chaos that kept them from
greatness. Then came Ashkaari Koslun, a great thinker whose
teachings molded the kossith into the godless, disciplined Qunari."
"Tal-Vashoth usually stick together. Most are kossith. Since many in Thedas see kossith and
think 'Qunari', the Tal-Vashoth are often forced into a life of banditry and mercenary work,
unaccepted and unable to find safer work."
"Elven broodmothers give birth to shrieks.
Dwarven broodmothers spawn genlocks. Humans birth hurlocks
and kossith birth ogres."
"Spawned from kossith broodmothers, ogres are huge and broad with long, muscular arms and massive
curved horns atop their heads, which they use to viciously charge attackers."
"Ogre: One of the massive, horned breed of darkspawn derived
from the kossith."
That should put a stop to all the pointless attempts at corrections I hope. Use Kossith to refer to the race if you wish, World of Thedas does.
On topic: For Kossiths to sell themselves in that way? Do they even fully understand the concept? I curious too, to learn if they have a sense of pride against such a thing.
