I showed someone from my world a vision of our past, but the process of creating the vision also blocks electrical signals from outside, so I apparently stopped Acumen and the Defense Force from being able to read our life signs. I didn't even know they were tracking life signs, but I got quite a lecture about it, and that power was blocked by Acumen. It was a simple mistake - hardly worth sending out two Defense Force members and bringing us in for questioning, right?
