The Observer Effect

The stonecutters are the Kha'lanka! Closer study of their remains has shown that they were crystallized when their silicon-based molecules bonded with oxygen, forming quartz. The Kha'lanka habitat is at a depth where oxygen does not occur naturally. They developed as an anaerobic lifeform, suffering horrendously excruciating and drawn out deaths on exposure to air. Surveys of the tunnel system confirm the suspicions of our scientists - until the first archaeology team pierced the tunnel system, the Kha'lankah civilization was still alive and thriving. Our discoveries here have led to the invention of a technique where crystals are manufactured synthetically by oxidating artificially grown silicon-based cell-clusters.

When this event fires, you can choose between these 2 options:

• Remarkable.
• We had better avoid the "Can't Breathe" adaptation.
