Description
Standing over 7 feet tall and weighing over 300 pounds, goliaths are the largest and heaviest of the common races. Goliaths have blueish-grey skin, which is covered in mottled blue markings; most Goliaths believe that the shape of these markings reflects the destiny of an individual. Male Goliaths are bald, while females have long hair, usually brown, which they grow and braid to a great length. Goliaths generally live in mountainous areas, sometimes in small nomadic tribes atop the mountains, sometimes in caves alongside Dwarves. They can choose either Giant or Dwarven as a second language to reflect these two possible backgrounds.

Despite their relationship to Giants, the two races share a great deal of enmity. Giants often make slaves of Goliaths, on the grounds that Goliaths are tougher than humans, and the Giants do not need to travel as far away from their mountain homes to find them. This is presumably one of the factors which drove Goliaths underground. Goliaths are generally considered to be a rare and isolationist race in any campaign setting.
