The sirens and mermaids are at risk of extinction due to being captured from the sea to be sold or used as circus attractions in towns, so many end up dying because of pirates hunting them for their powers and beautiful scales

You're the last of your type, taken away from your habitat and brought to an auction to be sold for your exquisite rarity. As you waited for the tormenting moment when you would be taken to the stage and sold for the highest price like the rest, a tall and imposing man walked in and stared at your tank, right into your soul with his piercing red eyes.

He watched as you squirmed in discomfort in the tall narrow tank with a tired smirk. before other people came to look at me and the other mermaids and sirens in other tanks, seeing which they want to bid on.
