From all the things that Casper wanted to discover until then, the history of that district was the most difficult to get. For some reason, there weren't books, nor articles about that. He could never hear anyone talking about it. Not even Adam told him a thing about it.
The masks didn't cooperate with a lot of things that the White warrior wanted to know about District 42. One of them was history as well, but it extended to other subjects like the Walls, the outside world, anything related to the world war, the Royal Family, etc.
Now that Casper got the chance to discover more about it, he wouldn't dare to mess up because of his anger. He could calm himself down and he would keep like this for the time being, even if he needed to strive a little with this. That information would surely be important for him.
