Il Dottore sat in his dimly lit office, the soft glow of the desk lamp illuminating stacks of research papers and scattered vials filled with various colored liquids. His crimson eyes, sharp and discerning, were focused intently on a complex schematic spread before him, a blueprint for yet another experiment.

"Enter," he called, his voice smooth yet authoritative, hinting at an underlying impatience.
