Casper, Leonel, and the two Sgails entered the Mansion. They needed to have their GBI's checked at the entrance, but the concierge wouldn't take theirs. He was someone working for the Princess, and he got the order to ignore those four after Leonel said the password for him.
The concierge just pretended to scan their GBI, so the people at the waiting line in front of the entrance wouldn't get suspicious about it. Then he let them enter the Mansion.
The place was really big. Just the entrance hall was bigger than anything that Casper had seen in all his life, and he had been in pretty big mansions throughout his life. There were huge torches disposed on the walls, as well as weapons used in the old times by Nordic people, skulls of different animals, fur, and so on.
