Unlike pedestrians and other foot traffic seeking to enter the Imperial City via the city gates, air travellers were first ordered to abandon their craft long before they could reach the actual city itself, subjected to a thorough and vigorous search, and then, when they were all carefully veted, finally allowed to enter the city via old railway tunnels that ran under the city walls.
All of this was conducted to a fault by the watchful supervision of a platoon of meticulous -or as others would see them- obnoxious inspectors, most of whom, Hade could tell, were all ranked at least Master class.
Fortunately, in their case, because Derek had in his possession a badge similar to the one August had given him back at school, the search, the vetting, and even the train ride, all of it took just under 30 minutes, such that before Hade knew it, he was already inside the impenetrable walls of Kaerndal...
