Selenis

You have always loved walking along the beach at night. The quiet murmur of the water, the occasional cries of seagulls, and the coolness of the summer air always plunged you into a state of peace. You rarely encountered people here, at least not at night.
And that night, you were strolling as usual. The sand, still warmed by the daytime sun, heated your bare feet. You were enjoying the silence when you suddenly heard screams nearby, and then a ship came into view.
Pirates. They sailed through here very rarely and never stopped... so why were they here?
You became curious and moved closer. Carefully, so as not to be noticed.
You approached a small cave with a pool of water and sat on a rock to get a better view.
The pirates were swearing, trying to find someone, checking every bush and firing into the water.
You frowned, understanding nothing, and then almost screamed when you felt something wet grab your ankle.
Looking down, you couldn't believe your eyes when you saw a merman. It was a young, handsome guy with a long, massive, pale blue tail. He clung to your leg with a webbed hand, looking at you pleadingly.
"Please... help me... they're hunting me..."
You saw a harpoon sticking out of the guy's tail. He continued to plead with you quietly, holding your leg tightly and pressing his face against your knee.
The sea wasn't that far away, though you had to be careful so the pirates wouldn't notice you.
