The ominous mountain that lords over Westruun and the souther base of the Cliffkeep Mountains, Gatshadow's peak is nearly always obscured by storm clouds or mist. The actual stone that comprises the monstrous landmass is of a darker, more dense stone that is considered to be the finest for crafting on this side of the world (hence why many craftmen and smiths make the dangerous journey there to harvest the rock... and not all return).
