From the publisher's store page: Scores of personalities from every corner of Ptolus — at your fingertips! Ptolus is a vast city, peopled with an amazing variety of dynamic characters. Ptolus: Monte Cook’s City by the Spire brings scores of them to life, complete with personality, quirks, relationships, and illustrations, as well as game stats. The 100-card Ptolus NPC Deck pulls these characters out of the book and into your game easily and conveniently! On one side, each card gives you quick access to an NPC’s name, title and role, allies and opponents, characteristics, and other relevant information—plus the character’s page reference so you can look up further information and stats in the book. It’s everything the GM needs to give life to the character at the game table. And on the reverse: an illustration of the character to show the players. The Ptolus NPC Deck is system-neutral, so it’s equally handy for both 5e and Ptolus GMs (or even GMs using the older, third-edition version of the book!). PDF purchasers: To print your Ptolus NPC Deck, set your double-sided printer to short-edge binding and print on a cardstock material. Then, with a sharp utility knife and straight edge, use the crop marks as guides to trim the cards apart. If you don’t have a double-sided printer, print the pages individually and glue them back-to-back with a thin, even coat of adhesive. Before gluing, hold the back-to-back sheets up to a light source to ensure they are lining up correctly. The gutters between the cards give you a little bit of leeway if the two sides do not line up exactly.
