What is wights?

As an AI language model, I can provide information on the topic of wights in various contexts, including literature, mythology, and folklore.

Wights are supernatural beings that hold different meanings depending on the cultural traditions they are present in. In Old Norse mythology, for instance, wights (or "vettir") were believed to be the spirits inhabiting various landscapes, such as forests, rivers, and mountains. They were usually associated with either good or evil and could either help or harm humans based on their actions towards the natural world.

In contemporary fantasy literature, such as J.R.R. Tolkien's The Lord of the Rings, wights represent undead beings that can either be allies or foes to the protagonists. These characters are depicted as ghostly apparitions that haunt tombs and abandoned places, seeking revenge or guarding treasure.

Overall, wights are a recurring theme in mythology and literature, representing the relationship between humans and the natural world, death, and the supernatural.
