This caused the Orc's skin to become green or greenish, which unfortunately for their species was passed down genetically. Originally, the Orcs were brown-skinned, but due to their discovery by the Burning Legion thanks to the members of the Eredar who would soon become known as the Draenei, they were purposefully corrupted by Kil'jaedon in order to aid in the defeat of the Draenei.
Most of their species currently reside on the planet Azeroth's Kalimdor continent, in an area they have named Durotar. Naturally, they lead a shamanistic culture, although this was temporarily brought to a halt due to the Burning Legion's influence. They are notable for smelling so bad that undead beings find them detestable. Orcs are a race of bipedal sapients who are indigenous to the planet Draenor, which has since been destroyed and transformed in Outland.
