"No, we've checked the logs. It actually happened a day after their raid here. It seems they slipped at least one person in, during the confusion, and simply walked him out in disguise, later. But, yes, that is a concern. We suspect his ability doesn't allow for long-term storage of power; if anything had been trapped, it would have triggered or dispelled long ago, or isn't dangerous enough to be a concern. They didn't stick around long enough to have gone anywhere to cause serious damage. With his abilities, anyway. We still had someone infiltrate our security, so we need you all to be vigilant, and let us know if you see or sense anything unusual."
