- ―Description of the Wild Waste Lands[src]
The Wild Lands of the North, also called the Wild Wastelands of the North (or sometimes informally nicknamed "Giantland") was a vast and virtually ungoverned region located in the far north of the Narnian world. The Wild Lands of the North are bordered to their south by the North River, which separate the region from Ettinsmoor. To its east, the area gives way to the Great Eastern Sea (containing the Merpeople's sea nation); it gives way to an arctic tundra and to mountains in the north and west, respectively. To this wasteland's west is the Western Wild region and even further north is an Icy Tundra, which in turn borders Aslan' Country.
The Wild Lands of the North are a highland region characterized by mountains and high hills, treeless and desolate health and moors, deep and narrow ravines and rivers (which freeze during winter months), and stony valleys. Its rough and very windy terrain and colder climate make it inhospitable for many.
It is therefore sparsely-populated and contains very few roads or civilization.
What little inhabitants who do reside there include Giants, many of whom lived in the House of Harfang, a large castle surrounded by a moat, just north of the Ruined City of the Giants (also called the "City Ruinous"). The ruined City is the remains of an ancient giant city destroyed in a war. Among that city's ruins was a known entrance to Underland.
Giants at Harfang, along with the gnomes or "earthmen " (living beneath the region in Underland ) appear be the only permanent, organized civilizations that persist in the Wild Lands of the North. Dragons are also mentioned as roaming in larger numbers in this region. Powerful witches who have attacked Narnia have come from the Wild Lands of the North.
The first of these witches is Jadis (the White Witch), who was banished to the Wild Lands of the North by Aslan for 900 long years she waited to make her return to Narnia.
Jadis assembled much of her army here. Races of dark creatures loyal to the Jadis are said to have once lived here (and perhaps still did though in small numbers by the series' end). These include Minotaurs, Ogres, ghouls, boogles, and cyclopes, hags, spectres, etc.
The Wild Lands of the North are considered "witch country" known for enchantment and dark magic. Besides Jadis, another named northern witch is Lady of the Green Kirtle (or the Queen of Underland ). The region is therefore regarded with fear and reasonable superstition by many Narnians.
During the Age of Conquest, the Giants of the Wild Lands of the North, along with the Ettins (a southern race of Giants living in Ettinsmoor), became intelligent species (presumably meaning they learned reading and writing), and together built a civilization. During the Age of Winter the Ettins became uncivilized, but the Giants, further north in the Wild Wastelands, remained mostly semi-intelligent. In the Golden Age, unlike Ettinsmoor, they were a forcible opponent to both Narnia and their ally Archenland. Although sometime in the Dark Age, their once-great civilization was reduced; the ruined city outside Harfang is evidence of a downfall. Harfang's giant community is all that remained of the giants' formerly developed civilization, which in its heyday likely rivalled Calormen. In the Telmarine Age, it was little more of a nuisance then Ettinsmoor.
In the Age of Exploration, it was in the Wild Waste Lands of the North that Eustace Scrubb, Jill Pole, and Puddleglum first met the Lady of the Green Kirtle and, unbeknownst to them at the time, Prince Rillian, who at the time was clad in a suit of black armor. The lady told Eustace, Jill and Puddleglum of the house of Harfang, home of the Gentle Giants, and told them to visit and gain entrance for the Autumn_Feast_(books). They would be well-fed, bathed, clothed, and made comfortable, which was welcome news to the two children.
Once at Harfang, Jill saw the words "UNDER ME" etched onto the top of one of the skyscrapers of the Ruined City from her massive bedroom window. On their way to the castle, they had previously crossed on their way to the castle, and soon realized it was one of these letters that she had fallen into during their trek to the house. It turned out that the giants really wanted to eat them for the feast, so the children and Puddleglum left quickly, but were chased. As they were running, the ground collapsed under them, and they slid into a tunnel, which led them into Underland.
In the Later Ages, king Tirian may have declared war on the region for Harfang's theft of Narnians for the Autumn_Feast_(books).
