Case 1: On June 7th, 2199, Dmitri Okafor-Lindqvist, age 54, was found reduced to calciumite ash in his sealed living quarters in the Laceworks. The room's fire suppression system did not activate. The ambient temperature in the room never exceeded 22 degrees Celsius according to the environmental monitoring system. The chair he was sitting in was undamaged. The book on his lap was unburned. The man was powder.

Case 2: On September 30th, 2199, Hyuna Mbeki-Desrosiers, age 38, was found in identical condition in a private meditation pod at a wellness center in the Circuit. The pod is sealed, climate-controlled, and monitored by seventeen sensors. None of them detected fire. None of them detected temperature elevation. The pod's internal camera — which records continuously — shows Hyuna sitting cross-legged, eyes closed, meditating. At 14:23:07, she is alive. At 14:23:08, the camera captures a single frame of white — not fire, not light, just white, as if the sensor was overwhelmed by something outside its range. At 14:23:09, there is a pile of calcium ash where a woman was sitting. One frame. That is all it took.

Case 3: On January 12th, 2200, an unidentified male was found in a maintenance tunnel beneath the Spine, reduced to ash in the center of the corridor. The tunnel floor — reinforced ferrocrete rated for temperatures up to 2,000 degrees — showed no heat damage. No scorch marks. No thermal signature. The ash was contained in a perfect circle, 1.7 meters in diameter, as if whatever occurred respected a boundary.

Three people in sealed environments. Three piles of ash. Zero fire. The combustion required to reduce a human body to calcium ash exceeds 1,400 degrees Celsius sustained for two hours. Whatever happened to these people was not combustion. It was something else that left the same result. We have no theory. We have no leads. We have three circles of human powder and the growing suspicion that we are investigating a phenomenon that does not care whether we understand it.
