One of the bishops on the white side is: ASSISTANT DIRECTOR WALTER SKINNER

Assistant director Skinner is basically a good man stuck in a bad situation. He supports the work of the team, but has to answer to a higher power that does not. Often, to his own detriment, A. D. Skinner will risk much to help.

On a more practical level.
I needed some way of easily identifying not only the character, but also what role on the chess board that character is occupying. In other words, the player must have a simple way of being able to tell the knights from the bishops. Therefore I chose those who wore suits as bishops, and those who don't, as knights.
