Fourth Compendium

The Fourth Compendium is the phase of writings between the Third Compendium and the current era.

The Fourth Compendium era corpus is significantly smaller than the other eras, yet it contains interesting new innovations like codifying temples and introducing the clerical ranks.

The corpus is as follows:
 * Commandments
 * Sacred Architecture Part I: Shrines and Temples
 * On Knighthood
 * On Clerical Ranks
