Terry Pratchett said this quote

“ Fantasy imposes order on the universe. Or, at least, it superimposes order on the universe. And it is a human order. Reality tells us that we exist for a brief, beleaguered span in a cold infinity; fantasy tells us that the figures in the foreground are important. Fantasy peoples the alien Outside, and it doesn’t matter a whole lot if it peoples it with good guys or bad guys. Putting ‘Hy-Brasil’ on the map is a step in the right direction, but if you can’t manage that, then ‘Here Be Dragons is better than nothing. Better than the void. ”
