Fantasy / Sci - Fi
Fantasy is a genre that uses magic and other supernatural phenomena as a primary element of plot, theme, and/or setting. Many works within the genre take place in fictional worlds where magic is common. Fantasy is generally distinguished from science fiction in that it does not provide a logical (or pseudo logical) explanation for the scientifically impossible events that occur, though there is a great deal of overlap between the two.
