Wights are supernatural beings often found in folklore and fantasy literature. They are typically depicted as undead creatures, resembling humans but lacking their vitality. Wights can be associated with various forms of magic and are often linked to themes of death and the afterlife. In some stories, they serve as guardians of ancient burial sites or treasures. In popular culture, wights are prominently featured in series like Game of Thrones, where they are portrayed as reanimated corpses controlled by powerful entities. Their characteristics and abilities can vary, but they are generally seen as malevolent forces that pose a threat to the living.
