The Greenskins are a race consisting of two races; Goblins and Orcs. The mighty, but very bright orcs are, with rare exceptions, the leaders of the Greenskin Clans. The more numerous and a bit smarter goblins usually serve them unquestionably. Once, all Greenskins were united into one unstoppable force led by the Khan - Greatest Orc who ever lived. But as he died, arguments rose and the Khaganate seperated into small countless Greenskin Clans, spread around Corinth. Disunited, they pose no thread to the Kingdom of Falmir.
The Greenskins have their own ancient language, but most of the clans have developed a language that is mixed from that language and the one used by humans through time.
