How was your training?" ■ About the Index A Finger that values Prescripts above all else. They primarily use swords, and each member is issued a sword suited to them via a Prescript. Prescripts must be fulfilled at all costs, yet success or failure depends on the interpretation of the Prescript. Those who fail are punished by the Proxies. The crucial Prescripts are created by a loom spinning incoherent lines recorded by a pendulum reacting to the vibrations of the entire City. These lines form words, which are then sealed with wax by the Weaver to complete the Prescript. Messengers deliver them to Index members and residents of the Backstreets under Index protection. If the Index seal is correctly applied, even a forgery is treated as a real Prescript. However, forgeries are always detected, and the fate of the forger is left to the Prescripts (whether they are overlooked or punished depends on the Prescript).
