The Codex's pages illuminate with aurora-like radiance when opened, each depicting moving holiday characters in cinematic tableaux that shift and interact across the translucent vellum. Bound in leather formed from crystallized acts of brotherhood, with film-reel ribbon bookmarks in forest green, crimson, and gold, its ink flows like liquid snowmelt mixed with starlight, constantly rewriting itself to reflect new character combinations. The tome's weight fluctuates with the collective spirit of the leagues, growing heavier with accumulated charitable deeds, yet always opening effortlessly to reveal the precise character ensemble needed for each unique bag tag illustration.

The Character Codex functions as the authoritative source that defines which cheerful elves, mischievous green creatures, Victorian ghosts, small-town townsfolk, magical train conductors, and joyful winter spirits converge in each cinematic moment, ensuring every bag tag tells a distinct chapter while maintaining narrative coherence across all ten leagues. It actively consults its own illuminated pages to compose scenes that reflect player achievements and league progression, manifesting appropriate tableaux where archetypes throw discs together, celebrate putts in tandem, create chaotic comedy, or share heartwarming moments across richly detailed winter environments.
