Fault

A fault is a plane in the crust: stone that has already broken, where Pressure can load until a Quake runs. A Stratum can be offset. A Mountain can be raised along it. A Cave can open where the crack widened.

Fault is not a card type. It feeds Pressure first, then Stone. Threshold takes the crossing in the rock. Crush is the failure; this page is the seam that fails.
