After her father had sealed her brothers away, Sakura told King Xenoah why they were there.
"The only ruin I know of is below the castle, but no one has been able to get past the puzzle," said King Xenoah as he led them to a large chamber underground.
"You have to be kidding me," said Touya as he noticed nine large squares with nine smaller ones in each square. Some of the small squares also had numbers in them.
"Do you know what this is?" asked Lucia.
"It's a game called sudoku," said Touya before using a spell to fill in the blanks.
"There we go," said Touya as he finished. The wall before them then vanished in a bright flash of light.
"Just how many of these are there?" asked Hildegard as she noticed another wall. Three walls later, they had found the teleport circle.
"Time to see where this leads," said Touya before they entered the circle and being engulfed by a bright light.
"Whoa," said Touya as they found themselves in a giant library.
"Where are we?" asked King Xenoah.
"You are in the Library of Babylon," said a girl as she approached them.
"My name is Touya, I'm already in charge of four other pieces of Babylon," said Touya.
"My name is Irsifam, and I know who you are," said the girl.
"You do?" asked Touya.
"I'm able to see through the security of the other pieces and have watched as you found the others, and I recognize you as the new master," said Irisfam.
"You might find this useful," said Irisfam as she handed Touya a book.
"There are some spells that might help you inside this book, and please feel free to look at any books that you wish," said Irisfam.
