From the introduction:
120 gorgeous full-color cards for use with the ZEITGEIST adventure path. Each card features an NPC illustration; these are left unnamed, with a number key in the bottom corner, so that you can use the cards for other games. A pair of cards at the end of the deck provides the master index.
The card set is useful for both Pathfinder and D&D 4E games, with alternate stats on each side of the card where appropriate.
This set is for the second and third acts of the ZEITGEIST adventure path.
The deck includes:
46 NPC portraits
20 "red herring" portraits - NPC illos which can be used at any time so that players don't imemdiately realise that "having a card" = "important NPC".
43 items, rituals, and spells
9 Martial Scientist techniques
