Crimson Barks

Crimson Academy is a high school formed from an old factory building in London that is dedicated to keeping the members of The West Wing concealed from the public eye.
These people, called Fedorins, aren't a very large group, yet still they manage to cause a corruption when socializing with the students and the townspeople.
Not only are they a mixture of Assassins, spies, and detectives, but they also Serve as protectors of most advanced technology, in which it is typically sold to the to the rich and politically Powerful.
The fedorins only get a small section of the school, but it happens to be one of the most updated areas. Despite that fact, many rumors cause many of the other members of the school to be frightened of the peculiar section.

One of the more popular rumors was put into a phrase;
"Thus being a fedorin, we do as the fedorins do..."
Which refers to a certain hobby of theirs.
Pranking.
Now, it sounds like a simple game to those who have no idea what they were getting into, but when seen, the game was like war.
People who suffer the serious game of theirs often come back with bloodshot eyes, shaking. Others have permanent affects of the materials used in the 'pranks', usually a stutter or screams in the night, night terrors, odd phobias, or the like. Some never even came back

Though a lot of rumors were true, false ones did exist.
For instance, the other wing members believe their dangerous sport is only used on those other than their own wing. But in reality, they do it to eachother more often, making other victims rare compared to themselves. And they also go easy on the other students (even if it still seemed extreme for mere mortals.). The real deal they kept to themselves.
Screams that were heard are typically from the fedorins, not the mortal victims.
