Tulnukid

Tulnukid is a fictional concept, appearing in the science fiction novel "The Left Hand of Darkness" by Ursula K. Le Guin. In the story, tulnukid refers to a specific type of indigenous dwelling on the planet Gethen. These structures are notable for their organic, often subterranean design, blending seamlessly with the natural environment of Gethen. They are typically constructed from materials readily available on the planet, such as ice, snow, and hardened earth. Tulnukid are adapted to Gethen's harsh climate, providing insulation against extreme cold and protection from the frequent storms. Their construction often reflects the nomadic or semi-nomadic lifestyles of the Gethenian people, with some tulnukid being temporary shelters while others are more permanent settlements. The concept of tulnukid emphasizes the deep connection between the Gethenians and their world, highlighting their ability to live in harmony with its challenging conditions through ingenuity and adaptation.
