Zhenya had a quick think about the question. She didn't really know why he created it but she wanted to take a guess at why it was built and structured the way it was. She raised her hand and said, "Professor I think... that when he made it he put all the tunnels and dead ends in it so that whatever it contained couldn't get out. And... maybe whoever was unfortunate enough to find out how to get there, he wanted to make sure they didn't get back out and reveal the secret," she said.

Well, if there is a way in there is usually a way out, she knew that, but she thought it could be difficult to find the way out if the chamber itself was so big. She doubted there was an exit sign.
