Kor

These grey-skinned nomads are often seen wandering from community to community typically living off the land. Most of these white haired people prefer living adjacent to great peaks of large mountains. The eyes of the Kor are most often white with no pupil or iris. It is not the mountains per say that the Kor enjoy but instead they relish the vast openness of the sky.

Wandering Craftsmen

They have strong natural craftsmanship and occasionally bring products of their craft to market in exchange for similar objects from other cultures to learn of their methods of crafting. When wandering the mountains, a group of Kor will often walk into the territory of Goliaths and in exchange for their hospitality the grey skins will craft some weapons or armor. Communities of Goliaths more often than not look forward to a wandering group of Kor happening by as a goliath's craftsmanship is not as refined as a Kors might be.
While the grey skins do not possess any innate means of flying, this does not stop them from pursuing a means of doing so. The Kor have developed a contraption called a Kitesail which is similar to a hang-glider that allows them to soar through the sky. Some use these gliders as a form of sport as well as hunting. Others using them as a means of traveling once they reach a higher altitude. The kitesails are designed in such a way that they can quickly be assembled and taken apart so they packing them away isn't too cumbersome.
Rope is considered to be an extension of a Kor's hands. They possess superior handling and use rope for climbing, making ziplines and also using grappling hooks in combat.

Silent and Superstitious

There is a Divine among the Kor named Nahiri who angered the Elemental Prince of Air, Yan-C-Bin during the time of The Great Clash. Since the end of this event, the Kor people have been tormented by Yan-C-Bin's minions, the Kenku who have been hunting Nahiri ever since to lift their curse. The Kor believe that the Prince of Air is capable of hearing all words spoken outdoors since they carry on the wind. Because of this, the Kor developed a silent form of speech using their hands to carry a conversation. To keep their location a secret, most Kor will not openly speak outdoors for fear of the Kenku being alerted and sent to find them.

A People Divided

Nahiri and those that followed her after The Great Clash sought refuge underground and began a new way of life. In the years to come Nahiri would teach her followers the way of stone forging which would allow them to manipulate and sculpt stone using magic. After many years below ground the stone forgers eyes would develop grey iris which would adapt allowing them to see in the dark. The way to identify whether a Kor is of the earth is if they have grey eyes compared to the Kor of the sky who have white eyes. Kor of the earth also have have a more light grey skinned compared to those of the sky who have a more greyish blue skin tone.
