Backgrounds and Specialties

From Introduction:

These rules provide options for fleshing out PCs (& NPCs) beyond their ability scores, race and class abilities. The options here provide some minor benefits in terms of game mechanics, but the main intention is to provide some structure to help players customize their characters.

Each PC (and at the DM's option, each major NPC) can select one background and one specialty from the following lists. Of course the lists can (and should) be expanded or modified to accommodate the needs of the DM's campaign or inventive player ideas.
