The ability to monitor the mysterious man came courtesy of the Vice President's familiar. Alice's black owl, an enigmatic creature with an uncanny intelligence, had been stationed near the barrier as an extra precaution. They weren't foolish enough to rely solely on the barrier, which, while potent, could only detect the presence of intruders without specifying their numbers or actions.
Equipped with a small, discreet camera around its neck, the familiar served as their eyes and ears. Its role was crucial—not only could it relay live visuals, but it also had the rare ability to phase through objects, allowing it to bypass barriers and other magical constructs.
When the man appeared, the familiar had immediately alerted Alice, its connection with her ensuring instantaneous communication. Sensing the potential threat, Alice directed the owl to follow him into the restricted zone, its phasing ability enabling it to slip through the barrier undetected.
