From the preview:
In the mountains of the Northlands live the Gangr giants - the stunted, fifth-generation descendents of the cursed Jotuns.
Despite the Dwindling Curse, they still stand almost three times the height of a man and possess tremendously powerful muscles.
Armed with a simple tree branch, the Fjellgangr becomes a terrifying menace in melee as he thrashes around, potentially hitting all enemies within the model's two-inch melee range with each attack. The Dwarves and Skannfyrd of Nordgaard are glad to count them as allies.
