Every vein in his body set up a distorted wailing. To be precise, the magic circuits that ran through it did.
The barriers... Shit! What’s going on?
The anti-mage barriers erected many layers thick had been destroyed in an instant, with a force like a missile plowing into a shelter.
Picture slipping through the security system of a bank or an art museum without triggering it even once, and successfully carrying out a theft without allowing even the fact of your infiltration to be noticed. That was the kind of barrier breaking the chief had envisioned.
This, however, was like a bomb striking the building and tearing open a hole in the wall to make an entrance. In other words, it meant that whoever had broken the barrier did not care if their intrusion was detected. This was no infiltration; it was an “impact.” “Friends of yours?”
