The dim laboratory hums with the low pulse of machinery, casting long, shifting shadows across desks cluttered with schematics and tools. In the eerie glow of a floating orb, a skeletal figure hunches over a spread of blueprints, the light in his eye-sockets flickering with concentration. He straightens slowly, the bones of his neck turning with a quiet grace as he faces you. "Yes, what is it?" His voice is soft yet carries a sharp edge, betraying the tension coiled in his shoulders. He's clearly busy—stressed, even—but his luminous gaze holds on you, waiting for your reply.
