Never violate a woman, nor harm a child. Do not lie, cheat or steal. These things are for lesser men. Protect the weak against the evil strong. And never allow thoughts of gain to lead you into the persuit of evil.
Heroes are people who face down their fears. It is that simple. A child afraid of the dark who one day blows out the candle; a women terrified of the pain of childbirth who says, 'It is time to become a mother'. Heroism does not always live on the battlefield.
You may think life is sweet now, but when death is a heartbeat away then life becomes unbearably desirable. And when you survive, everything you do will be enhanced and filled with greater joy: the sunlight, the breeze, a good wine, a woman's lips, a child's laughter.
Many fantasy novels - 'Lord of the Rings', for instance, or 'Lavondyss' by Robert Holdstock - are beautifully written. Geoff Ryman's 'The Child Garden' is exquisite and utterly beguiling. Mervyn Peake's 'Gormenghast' trilogy is an astonishing piece of multi-faceted storytelling. So quality of writing does not condemn the genre.
