While the players each control a single player character, the narrator is in charge of all of the characters and monsters that the players will meet on their journeys. These characters are non-player characters (or NPCs). The narrator's task is to believably represent the behaviors of all of these characters.
NPCs fall into several broad categories:
NPCs should effectively be treated like player characters from the perspective of gameplay rules, with the following exceptions:
The Bestiary section defines a set of templates that cover what a generic NPC of a certain type looks like. This section does include mortal race NPCs of a variety of professions. Unless a character is an important character or villain, using these templates directly (or with differentia modifications) will be sufficient.
For important characters, the narrator may wish to either use the player character sheet, or may heavily modify the appropriate template.
For villains, the narrator should use the rules presented in the Villains section for constructing a villain character.
