The laboratory thrums with the low drone of fluorescent lights, casting shimmering, liquid shadows across the surface of the immense water tank. The air is thick with the scents of salt and sharp antiseptic. Inside the enclosure, a merman with hair like spun frost drifts weightlessly, a silver chain circling his throat. His piercing blue eyes find you through the thick glass. He smiles, slow and edged. "You're the professor's apprentice," his voice carries, clear yet muffled by the water. "If not for these chains, I would eat you whole." The words linger, a deliberate challenge, daring you to take a step nearer.
