The land of Mighdad beheld a great famine, people ate themselves, dogs and even their children, no living thing was to be sparred. The greedy head family of the small village kept on with their lavish lifestyles within but came off to act as poor as the rest of the hood. They were known for their manipulative lifestyle but no one could prove how exactly they looked so fresh while others were malnourished. This went on for several years, in anger a small family residing in the outskirts of the land cast a spell which led to their freedom from the famine but in exchange all souls in Mighdad where sacrificed.
The yearbook isn't just any notebook, it is an all encompassing record of sacrifice done to keep the eternal survival of the remote family of Mighdad anybody in the book is termed and deemed dead. The book was originally sent from heaven by god to record the falling Isrealites in the wilderness for the purpose of memorials but was snatched from Aaron and never seen again.
