Series Quotes (page 19)
In the first book of my Discworld series, published more than 26 years ago, I introduced Death as a character; there was nothing particularly new about this - death has featured in art and literature since medieval times, and for centuries we have had a fascination with the Grim Reaper.
Terry Prachett
I think when people mean that Discworld books have become darker they really mean the series is growing up. In 'The Colour of Magic' most of the city is set alight. It's a joke, in much the same way that the Earth is destroyed almost at the start of Douglas Adams's 'The Hitchhikers Guide to the Galaxy.'
Terry Prachett
