From publisher blurb:
This 22-page PDF features twelve letters from various periods in a generic fantasy setting. These letters can be used to spice up treasure hordes, spur player characters toward their next quest, or simply provide a measure of verisimilitude to the DM?s world. Each entry includes a physical description, the entire letter, and any relevant background information and notes. Use these letters as is, or let them goad your imagination to create new ones.
Now includes each letter as a separate handout. Give your players one of these letters and watch as they try to figure out what it means. Special thanks to Mark Gedak for creating the handouts.
