When he heard his brother, the little prince tried to call for him. But through the sea of paper, the sound was so muffled that Legolas sounded as if he was under water. That was enough to draw Ramiren's attention to the heap of books behind the desk.

In a few minutes, his brother had managed to free him and asked, "How did you end up under there?"
