Fantasy is the genre of hope.
It’s the genre of the Grail Quest, where the King is the Land, where Lancelot can heal with a touch, where nine walkers just might stand against the nine riders that are evil, where a few farm kids set out from a small town between two rivers to stop the Dark One, where no man can defeat the Nazgul lord so good thing Eowyn’s on our side, where Aerin bests Agsded and Maur to free her city, where Tenar finds her name and Aang can save the world.
But if fantasy is the genre of hope, it’s also the genre of a particular kind of danger. To hope is to commit, and commitment’s scary because we’re never hurt so much as when we care. Saving the world is hard. You lose people along the way.
