First of all, thank you for your interest.
At the beginning of the game, you have 4 "Luxolith" index cards that are fully filled.
Only the name section of these 4 "Luxolith" index cards is filled because you only know their names and will try to find them on your journey.
Additionally, the completely empty index cards are for "Luxolith" that you will find using your imagination.
I will try to release a color version soon.
