We all know what this is. It's probably what attracted us to Fantasy in the first place. Pure magic and medieval societies which have not progressed technologically beyond swords and armor. Mostly. And usually the heroes don't need guns, because they have nasty wizards or little girls with magic wands backing them up.

Swords and Sorcery is fantasy in a primitive setting, where problems must be solved with both violence and magic. The archetype of the genre is Robert E. Howard's Conan, but the field, while littered with grey Conan wannabes, is capable of much originality. Adventure and confrontation are key words to the genre.
