/*
Tiers and Requirements

Pieces of scripture require certain follower counts, contruction value, and active caches in order to recite.
Drivers: Unlocked by default
Scripts: 5 servants and a cache
Applications: 8 servants, 3 caches, and 100 CV
Revenant: 10 servants, 4 caches, and 200 CV
Judgement: 12 servants, 5 caches, 300 CV, and any existing AIs are converted or destroyed
