From Introduction: Jumpers NPC 20-Packs are for JMs who need a few “extras” to populate their jumps. They are especially useful if you are running a jump off the top of your head or if your players strayed into uncharted territory of a carefully planned adventure and you need a new NPC on short notice. The following set of NPC cards were designed to be printed front to back with the main stats and physical description on one side and the character’s backstory on the reverse. They can be used with the perforated printer notecards available at most office supply stores or just printed on plain paper and separated with scissors.
