Please get rid of the notes that detail the Overwatch Council's rules and open the last page of the organization's references in book five.
Book five details many of the cases the Overwatch Council has dealt with over the years. The great cases of the past few decades are written there, complete with a thorough analysis of them. They focus on a wide variety of different cases; this includes how they first began, the progress that was made, the influences it had on certain sectors and how things ultimately wound up for each party involved.
