When he reached the wall, he turned his chair to the right and moved as close to the wall as he could. He pressed his right hand against the wall and the bookcase slid up into the ceiling. Behind the bookcase was a very narrow passageway that the girls had never seen before. They looked at each other, and then at the Professor.
"Professor, what...?" Jean started to ask, but he cut her off.
"All of your questions will be answered soon, Jean. Please, follow me quickly."
Without another word, he glided through the doorway and continued along the passage. The girls leapt to their feet and ran after him. The bookcase slid back into place behind them and the darkness surrounded them completely. The Professor quickly activated a light on his hover chair and told them to keep close behind him.
He told them that this passage was a maze that only he knew how to navigate and that it would take them many hours to get out on their own. Rogue laughed and said that Jean could simply blast through the walls with her telekinetic powers.
"The walls are made of solid stone and are about five hundred feet thick, Rogue. Even if Jean could damage them, it would take her several hours to blast a complete hole through them."
"Ah didn't know that, Professor. How long did it take to build this maze?"
