Doctor and Sarah examine glowing trisilicate

The Doctor and Sarah materialize near a freshly excavated Peladonian tunnel where Federation mining operations have violently exposed a sacred trisilicate vein. The Doctor instantly identifies the glowing crystal as a typical deposit, treating the find as geological curiosity rather than supernatural threat. His calm rationalism contrasts with the looming terror of Aggedor’s presence, setting the stage for the coming conflict between science and myth. The glowing vein pulses ominously along the cave wall, an inescapable reminder that reckless Federation excavation has awakened something ancient and vengeful among the miners. key_dialogue: [ DOCTOR: No wonder the Federation was so keen to mine. A typical trisilicate vein, that. ]
