Angor slowly climbed in the air. Five seconds, ten seconds, thirty seconds, one minute, two minutes… He had already lost count of how long he had been flying, and yet, he still had not reached the ceiling!
But that's impossible!
Angor clearly remembered, when there was still light, he saw the stone ceiling above him. It was high but totally reachable.
Or was he inside a building, not the maze? Now he flew outside and could no longer reach the ceiling? Not likely, because Angor could feel the air around him remain unchanged. If he was under the sky, he should not be inside complete darkness.
Angor considered in his mind. Maybe he stumbled into some kind of confusion spells? Was he moving in circles because of some ghost's trick?
Jon once explained a situation where people would walk within one place. There was no magic or ghost involved. When people could not feel their surroundings clearly, their instinct would make them move in circles.
