Homebrew Finfolk Species Details

While rare, finfolk are a natural species. From the deepest trenches of the oceans to tropical coasts, finfolk are able to live in any area with a large body of water. Finfolk in the waters can often be mistaken for casual sharks, and on land, commonly mistaken for a sort of lycanthrope.
Oceanic Beast
Finfolk are shark-like humanoids, standing between 6 and 7 feet tall and weighing 250 to 350 pounds. Finfolk vary in shape, some sharing heads with hammerhead sharks, while others may appear like a great white or mako. Finfolk are near indistinguishable by sex, except by other finfolk, and are typically muscular but have a fair amount of fat to better acclimate to the cold depths as well as webbed feet and hands for better swimming capability. Universal aspects of finfolk are their black, emotionless eyes that cause unease to most other races, as well as gill slits on the side of their necks. Finfolk typically wear small amounts of clothing but will by no means avoid using armor if it is advantageous.
Predatory Mind
While humanoid themselves, finfolk have no qualms of eating other humanoids. Finfolk do not seek out to eat other humanoids, but if hungry, and there are no clear, immediate consequences, finfolk will not hesitate to prey upon humanoids, especially in water where they know they have the advantage.
Finfolk live in tribes ranging from 20 to 100 members. Some tribes may be migratory, changing locations based on the seasons, while others stay within a specific territory year-round. Finfolk do not put value on intelligence but instead on strength. Each tribe is run by a chief that is chosen by combat or competitions, such as each member looking to lead hunting, and the biggest catch is elected as chief. The chief is advised by the elders of the tribe.
Insatiable Hunger
When the scent of blood is present, few finfolk can resist its call to them. If a finfolk is able to smell blood, they have an overwhelming urge to feed. If a finfolk succumbs to this desire, they view anything as prey, but will likely pursue the origins of the blood above others. When in combat, this can be circumnavigated to an extent, as the finfolk most likely already views whatever they are engaged with as prey, so potential allies may not be at risk.
Eerie Visitors
Finfolk have been known to visit port cities, seeking to trade things such as fish, sunken treasures, and other things that are either commonplace or of no use to them in exchange for weapons, armors, or other useful items.
Though Finfolk may not be averse to eating other humanoids, if they deem another humanoid useful they will put value on them depending on their usefulness, and may even grow attached and view them as a comrade instead of potential prey or a tool.
