The game contains … cards organized into thematic collections.
Names, dates, countries and identifiers (Q prefix) come from Wikidata, published under CC0 1.0 (public domain). Attribution is not required, but is provided here voluntarily. The short descriptions displayed on cards were written for the game.
42 cards use images from Wikimedia Commons, selected using Wikidata's image property (P18).
The source, author and license for each file are available in the card details. Licenses vary between files and are not interchangeable. When no free image is available, Codex uses a geometric placeholder illustration.
Cards represent documented historical and cultural facts. They do not express a judgment or position.
Credits have no real monetary value and cannot be purchased or traded outside the game. No payment is required. Booster backs reflect the pack's actual rarity.
