Not only that, I was able to pry the airline's flight paths from the Prime Minister. Both of them were not thrilled at the idea of a floating castle in the air, but after informing them that the magic would render it invisible and cause non magicals to turn away, they allowed it. Especially once I assured them that Avalon wouldn’t be floating above London. That meant all I had to do was ensure that a teleportation circle was set up for access and removing the labyrinth and I could get Avalon out of the ground.
