Goliath

The first goliaths lived on the highest mountain peaks — far above the treeline, where the air is thin and frigid winds howl. Distantly related to giants and infused with the supernatural essence of their ancestors’ mountainous home, goliaths stand between 7 and 8 feet tall and have a wide array of skin tones resembling different types of stone. Their hearts are infused with the cold regard of their frigid realm, leaving each goliath with the responsibility to earn a place in the tribe or die trying. Nowadays the goliaths often live in small clans or tribes living off of nature trying to survive in their harsh environments in Iaqari. Frequently battling giants and dragons that are a common sight in these lands. Though also in the harsh cold lands of Iaqari, there are a couple notable large cities or civilizations made up mostly of goliaths, often massive hubs for religious activity among the inhabitants of those lands.
