Hakland or Haakland is a homeland of the Haak people, located to the east of the Blue Mountains, which separate it from the Northern Kingdoms of Lyria, Aedirn and Kaedwen. It is geographically northeast of Zerrikania.
"(...) Whe know ever less of Haakland, safe its location to the northeast of Zerrikania. The people of that land are rumored to be the finest horsemen in the world, learning the art as babes before they even learn to walk. Though not referred to by name, they are also possibly mentioned in one of the apocryphal versions of Ithlinne's prophecy, which speaks of people that will come from the East like a storm, to burn, slaughter, and feast on the ruins, drinking from the skulls of their fallen foes." Bella Jande, "Tales and Legends of Distant Lands"
