The classroom wasn't decorated because it wasn't considered an official celebration; it was more of a tradition for this particular class to celebrate every 10 pages.

Adam walked into the classroom and found his classmates there. It seemed like, for the first time in a long while, the teacher was running late. With many doubts, Adam asked as he sat at his desk:

—Where's the teacher?

—He left a few minutes ago...— Bianca replied, trying to read the new pages of her learning book —He had to prepare some things for today's celebration.

—Still no sign of your powers, Adam?— Franco asked curiously. Adam's two classmates lived on the upper floors, so they hadn't received a magic book.

—No, I still don't know what the book did...— Adam replied, reciting the answer his godfather had forced him to say for the past 5 months.

The magic books given by the Sombrines had only one use, so only a librarian could learn the magical ability of the book. Once read, the book would disappear. On the other hand, the magic books from the bookshelves belonged to the shelves and could be used countless times. But a librarian couldn't take one and keep it unless they stole it to give it to another bookshelf.

This tale has been pilfered from Royal Road. If found on Amazon, kindly file a report.

That's why his godfather was afraid that other librarians would find out he still had his magic book and try to steal it. So, he had compelled Adam to lie every time someone asked him about it.

Some time passed, the kids got bored in their seats, and finally, Professor Aquiles had arrived, but there was a slight difference on his head: the face of a very tiny person, the size of an eye, could be found on his forehead. This was the magical ability that Aquiles had learned from the magic book, but the teacher still didn't know exactly what it was for, only that the tiny face could give him advice.

—Alright, everything is ready now— Professor Aquiles said —Today, you'll learn a bit about one of the most common creatures in this library: the Little Books, also known as messengers.

The three kids got excited; they didn't expect another special class as a celebration. The previous one had been very useful and fun.

—For that, we'll use the Little Books that live in the school— added Aquiles—Follow me, and I'll show you, but remember not to touch or talk to them without my instructions. The Little Books are pretty harmless, but the bookshelves that take care of them aren't, so don't disturb them.

The children followed the teacher attentively. Adam was somewhat excited; he knew that the bookshelves loved these creatures, but he had never seen one before.
