Arthur just smiled, as the explanation of any array would be such a complicated task even for a master like him.
"It's a tool that can conceal anything inside from the eyes of any outsider," he simply explained, without delving deep into any details, "it's called an array," he added, as he went ahead and collected the poles, starting with the central and main one.
Once he took this pole, the whole array crashed, and she could see the area that was hidden. After he finished collecting everything, he gave the poles to her as he said:
"Take Randy with you and Insert these poles according to places marked in this map," he gave her the map which marked the place of the poles. She just took the poles and didn't ask for more, as she felt how profound and revolutionary this array was.
She then headed outside the hall, where he remained holding the main pole in hand. He then looked for a hidden place, concealed by thick curtains, and inserted the pole into it.
