William returned back into his territory to not do anything else but have a long nap. He was indeed exhausted mentally and needed rest more than anything at this moment.
He let Thomas stay at any building except the seventh and central one. And yet, William slept in the open. He refrained Thomas from trying out the central building, as he expected the statue he wanted to be hidden in there.
Before he'd sleep, he made sure to make a rough copy of the entire arrays here for Thomas to use. It wasn't that hard to do this when he got the key to this place. And all he had to do was to spend little of his time studying this stone before copying the same writings over this key over another stone.
He could already grant anyone the ability to come in and out from this place. He did that before with Thomas when he let him go out and bring food over during the past days. But Remy wasn't here to grant her access, and he didn't want to waste his time giving others access when they'd join him.
