Barid considered the data with a dispassionate, analytical mind. "You're correct, the shields aren't designed to be perfectly impermeable; they're designed to allow small, natural elements, such as the meteorites that contain adamantine, to naturally populate the planes, as always. That said, nothing of that size or speed should have been able to pass through. I'll consult my records in greater detail, but I don't expect to find any anomalies; everything that passes through the shields, no matter how small, gets recorded. Any one of those should have generated a full briefing for me, within hours; I've been interrupted by object<em>far</em>smaller. Something is amiss. Any ideas?"
