So I'm getting to world build merfolk culture for the campaign I just joined. I really wanted a mermaid priestess and the GM went for it! This is Nelle (rhymes with bell, shell, etc.); the middle section of my artistic venn diagram. More pics of her (and campaign mates?) to come no doubt!
A little info on the merfolk culture so far cuz I'm having so much fun: their language has 3 parts - regular speaking, sonar, and sign language! Speaking for on land, sonar for long distance underwater, and sign language for up close underwater/on land.
Depending on the body of water they live in + genetics = their color pallets and features. Nelle is from a freshwater lake so her colors are more limited and her fellow lake-neighbors have a similar range of colors (greens, browns, you know lake colors).
Merfolk from a tropical ocean would have a wider range of colors and features! Think tropical fish; bright and way more varied design wise. But if a merm from a lake went and lived in a tropical sea for a long time, their colors could brighten! Reversed; colors could dull some.
