Encounter Guide: Bestiary Terminology

While many creatures are presented, you will often find it useful to choose only a few at any time, and add further detail to your chosen creatures’ lives in your world. You can add to or create their culture (if they have one), their eating, mating, and sleeping habits, create legends about them specific to your world’s peoples, and even modify them, perhaps adding special powers on occasion or special goals.

The Adventure Guide’s Handbook has more advice on populating your campaign world.
