When you would observe or infiltrate a location where you do not belong, spend a Momentum and blur the line between what is expected and unexpected. You take on the aspect of someone unassuming and invisible: a janitor, gardener, housekeeper, etc. So long as you collect information or remain an observer and do not take hostile action, anyone in the same Field as you overlooks your presence. This lasts until you take violent action, or until you leave the Field, whichever comes first.
