Fairy tale does not deny the existence of sorrow and failure: the possibility of these is necessary to the joy of deliverance. It denies (in the face of much evidence, if you will) universal final defeat...giving a fleeting glimpse of Joy; Joy beyond the walls of the world, poignant as grief.
J. R. R. TolkienKings built tombs more splendid than the houses of the living and counted the names of their descent dearer than the names of their sons. Childless lords sat in aged halls musing on heraldry or in high cold towers asking questions of the stars. And so the kingdom of Gondor sank into ruin, the line of kings failed, the white tree withered and the rule of Gondor was given over to lesser men.
