The Codices of Civilization were books written under the authority of the Quara'tun Covenant, defining the interactions between the Lith-Crillion and the peoples of the Mortal Systems. They outlined the methods of record-keeping and the monitoring of Creation's worlds and their lifeforms. Additionally, they established the rules for removing dangerous relics and items left behind from the Creation War (1486 DE - 8777 DE) and the Demon Spawn War (89 GE - 269 GE). The goal was to collect such artifacts, transfer them to the Crillion Comet, and then either store them in a secure facility or cast them into a nearby star.
