finfolk

Finfolk are a fictional race of merfolk appearing in various forms of folklore and popular culture, often depicted as sentient, aquatic beings with the upper body of a human and the tail of a fish. While the term "finfolk" is sometimes used interchangeably with "merfolk" or "mermaids," it can also refer to specific variations or cultural interpretations of these beings.

Historically, the concept of aquatic humanoids has appeared in mythologies worldwide, from the Greek sirens and nereids to the Slavic rusalki and the Japanese ningyo. These beings were often associated with the sea, its dangers, and its mysteries. They could be benevolent, offering guidance or protection to sailors, or malevolent, luring ships to their doom. Their appearances varied, sometimes described as beautiful and alluring, other times as grotesque or monstrous.

In modern fantasy literature, film, and games, finfolk continue to be a popular subject. Their portrayal often leans into either romanticized notions of a hidden underwater civilization or the more primal and wild aspects of sea-dwelling creatures. Their abilities can include breathing underwater, controlling water currents, and communicating with marine life. The specific characteristics and lore surrounding finfolk can differ significantly depending on the creator's imagination and the narrative context. Despite variations, the core image of a human-like creature with a fish's tail remains a consistent element in their depiction.
