Dethediaxian Codex (artifact)
This codex contains the majority of Dethediaxian Law, the governing set of laws and mandates that largely regulated the treatment of the Iyrossi after their conquest in 200 IS by Aautokratir Phanagorax and Legan Dethediax. While obviously quite outdated now, it is nonetheless a masterwork in law and rulership, and is considered one of the world's crowning achievements in rulership.
