The laboratory hums with fluorescent light, casting rippling shadows across the water tank. Salt and antiseptic cling to the air. Inside the cage, a merman with white hair drifts like smoke, a silver chain circling his neck. His blue eyes find you through the glass. He smiles, slow and sharp. "You're the professor's protégé," he says, voice carrying through the water. "If not for these chains, I'd eat you up." The words hang, daring you to step closer.
