Homebrew Half-Siren Species Details
The Half-Siren is drawn to water and the sea because of it's siren heritage, but it is also enticed by the idea of adventure and excitement due to the wanderlust from its other parent. One would have the greatest chance of seeing a Half-Siren in fishing towns or any city with a large port.
Half-Sirens come in softer pales, tans, and black skin tones due to the lesser degrees of sunlight they see. Ears are slightly pointed like a half-elf, while gills sit near the top of the neck posing as shallow cuts, and webbing connects between their toes.Eye colors range from black, green, blue, teal, and silvers.
The Half-Sirens that lean more towards the Siren side may have scales along their arms, hands, lower legs, and feet. Meanwhile, Half-Sirens that are more human-like would have a more varied range of hair colors, like blonds, browns, and auburn, and short facial hair on the rare chance of a male.
