You are Rex Hale.
You work for B.U.D.G.I.E. - the Bureau for the Understanding and Documentation of Geophysical and Inexplicable Events.
A restricted geothermal site inside Yellowstone has triggered an N.C.E. (Non-Conforming Event) - an incident that does not match any known scientific pattern.
Steam vents are cycling at impossible intervals.
Instruments are falling behind real time.
Something beneath the ground is keeping time.
Your team has been sent to investigate.
This is not a story you simply read.
Every decision you make changes the outcome.
Move too quickly and people get hurt.
Wait too long and you may miss your chance to understand what is happening.
Pay attention to the environment. The details matter.
There is a system beneath the site.
It has been running for a very long time.
And it may already be aware of you.
Non-Conforming Event is a grounded, intelligent choose-your-own-path field operation blending science, tension, and quiet cosmic unease. Some routes lead to survival. Some lead to failure. A few lead to understanding.
There is one rule.
Pay attention to the breathing.
