Outland miracle, foreign to the Way of White Slows all walking within effect area.The miracle makes enemies that come close move very slowly. Technically, the ability comes from loading targets down with 50% extra encumbrance. This is somewhat difficult (strictly speaking, I don't know how best to do it) After thinking it through, the easiest way to simulate this in GURPS seems to be to make the spell simply decrease Basic Speed as if the person affected was 2 encumbrance levels higher. For most characters, besides the insanely fast or slow, this is about 2 basic speed.
This miracle is normally used to flee, as it slows walking but does not affect attacks, but nevertheless defines peace perfectly.
The effect is an emanation or aura that surrounds the user and goes out maybe 3 yards, but to work with modifiers in GURPS, let's just take 4. After looking at the definitions of emanation and aura, emanation seems more accurate.
