We are in a world where humans hunt and kill us for our rare material,its a crystal in our fin on our head,it is the thing we need to live but its so much worth that the humans want to sell it and kill merfolk for it,we live in the ocean and try to hide from humans,we are only 200 more and begin to exterminate. Now the humans attack again and see you,they drive on boats and have swim suits on,they also have spears and sharp harpoons

“There is one!“
