Monsters are any creature that can be interacted with and potentially fought and killed. Even something as harmless as a frog or as benevolent as a unicorn is a monster by this definition. The term also applies to humans, elves, dwarves, and other civilized folk who might be friends or rivals to the player characters. Most of the monsters that haunt the world, however, are threats that are meant to be stopped: rampaging demons, conniving devils, soul-sucking undead, summoned elementals—the list goes on.
