Coins rain down amid bursts of shocked laughter and startled, delighted gasps. The crowd has long forgotten the other market vendors at this chance to flirt with danger, to see something so rare and vicious here in their tiny provincial town. Humans love to feel a little fear when they know there is no actual risk and the townsfolk have thus blindly put their faith in the greasy man who gathers up their coins with one greedy hand while the other prods through the cage with a stick.
The creature in the cage can technically speak Common and should therefore be able to plead with her captor, or at least for sympathy from the crowd, but rage clouds her mind too much for her to do anything other than howl and launch herself at the bars. No one stands close enough to grab with her long claws yet still she tries, lashing her arm back and forth in the hopes of drawing blood. Her blue-gray skin bleeds where she has rubbed herself raw on the metal.
“Yep, wrestled this little bitch right out of the sea itself!” the man brags, jabbing her side with the stick. “She almost had me, too, but I was too strong for her! Not a man alive has ever caught one of these!” His words are lies; this oaf wasn’t even the one who cursed her into a human form, only a lucky idiot who stumbled across her while she was still dazed from the transformation. A feminine creature with long black hair and shark-like skin and teeth? He’d known exactly what she was and how much people would pay to see a monster like her up close.
“A real siren, incredible!” someone cries, while another asks with obvious concern, “Can’t they put a spell on you with their singing? Are we in danger?” The man scoffs at the question and, despite not actually knowing why she no longer has that trademark ability, uses it to his advantage. Kicking the cage, he laughs, “Yeah, but she won’t try anything funny on me. She knows who’s the boss here. Besides, I’ve been starving her down, she’s no match for me.”
Amid the tumult of voices and the siren’s furious snarling, someone whispers an unlocking spell. Even through her frenzy the siren senses this burst of magic and her keen ears catch the sound of the lock slowly turning. This time when she hurls herself against the cage the door bursts open and with a predator’s speed she leaps for her oblivious captor, howling in triumph. The impact sends him crashing to the ground and by the time he lands she’s already tearing at his throat with rows of serrated teeth. The humans who just moments ago had laughed and stared at her flee in terror, not a single one brave enough to attempt to contain her again.
Hunger partially sated, the siren tears off one of the man’s arms for further snacking and climbs to her feet. While she’s still unsteady on these strange human legs, used as she is to gliding through the water with her long, sinuous tail, she’ll adapt. With a little food in her belly she can finally think clearly for the first time since the awful spell that took her from her home was cast. Her thoughts burn hard and bright in their brute simplicity: Find the wizard. Make him reverse the curse. Eat him. Go home. Chewing on a meaty finger bone, the siren picks a direction and starts walking. She has no idea who this wizard is, where to find him, or how she’ll get him to lift the curse, but she’s not a creature of any particularly deep or complex thoughts and so this doesn’t much concern her. She can hunt and she can kill, and that’s good enough for her.
