*This is a small notebook. A broken arrow over a teardrop is drawn on the front cover, and a metal gauntlet with an eye is on the back cover. Each page is divided into two columns. The first column is labelled "D" with incrementing numbers from 1 to 30, and the second column is marked "S". Numbers in the S column are often crossed out and corrected, some are blank, though most numbers range from 100 to 500.*
