Hello my loves, I decided to participate in the Fairy Tale contest and I ended up creating this! It was based on Yara, a mermaid of the Indian tribe (story below)
I tried to create a contemporary version, and instead of using the original mermaid tail, I innovated with a version of 'transformation'

Iara is a beautiful young woman, sometimes described as having green hair, light brown or copper-colored skin (as that of an Indigenous Amerindian from Brazil, or of a caboclo) and brown eyes, connected to a freshwater dolphin, manatee or fish body (the Tupi word y did not have a distinct meaning, being used in general for any riverine or freshwater lacustrine place) who would sit on a rock by the river combing her hair or dozing under the sun. When she felt a man around she would start to sing gently to lure him. Once under the spell of the Iara a man would leave anything to live with her underwater forever, which was not necessarily a bad thing, as she was pretty and would cater for all needs of her lover for the rest of his life.
