Every* card of each of our NPC decks is a character. A portrait on one side compliments the background and personality info on the back. Imaginative story hooks abound in the descriptions, but of course you're welcome to change that to fit your campaign. Or just use them as portrait cards for your NPCs or PCs.
(* Each deck includes 1-3 cards for some combination of a title/cover card, checklist, alternate name ideas, ideas to vary the characters, etc.)
