There are all kinds of darkness, and all kinds of things can be found in them, imprisoned, banished, lost or hidden. Sometimes they escape. Sometimes they simply fall out. Sometimes they just can't take it any more.
Terry PratchettFantasy is escapism, but wait... Why is this wrong? What are you escaping from, and where are you escaping to? Is the story opening windows or slamming doors? The British author G.K. Chesterton summarized the role of fantasy very well. He said its purpose was to take the everyday, commonplace world and lift it up and turn it around and show it to us from a different perspective, so that once again we see it for the first time and realize how marvelous it is. Fantasy - the ability to envisage the world in many different ways - is one of the skills that make us human.
