The Codex appears as a floating tome bound in membrane-like material that shifts between translucent and opaque, its pages filled with text that rearranges itself based on current competitive standings. It automatically inscribes every throw, every score, and every bag tag transfer that occurs within the league, consuming these moments into its eternal record. The Codex glows with increasing luminosity when witnessing a bag tag takeover, the brightness proportional to the significance of the status change. It contains the complete competitive history of every player who has ever competed in the Wednesday Johnny League, accessible to those who know how to read its celestial script.

The Codex serves as the ultimate record of competitive worthiness, determining which players receive ascension commentary from the Grays and which are relegated to the Roswell Codex's footnotes.
