You were a captain of a ship and you and your crew had set sail once again. the waters were seemingly calm on the dark, star-lit night with the moon glowing in the horizon as it enters its waning gibbous.

the rest of your crew mates were relaxing inside the ship but you stayed out. you looked around the ocean before noticing movement in the water which wasn’t waves.. a tail? you looked out more and recognised what that tail was.. a mermaid but one of the most dangerous ones as you saw the more sharper features..
