Conflict is a concept from narrative fiction. It refers to either the ambivalent emotions of the hero ("inner conflict") or the opposition by antagonistic forces that the hero encounters. In a group of heroes, the "inner conflict" may be disagreement between group members. An example for "inner conflict" is Gandalf being torn over whether he should use or destroy the ring. Group inner conflict happens when Boromir attacks Frodo. The Nazgul are antagonists.
