This is the Death whose particular sphere of operations is, well, not a sphere at all, but the Discworld… — Terry Pratchett
This is the Death whose particular sphere of operations is, well, not a sphere at all, but the Discworld, which is flat and rides on the back of four giant elephants who stand on the shell of the enormous star turtle Great A'Tuin, and which is bounded by a waterfall that cascades endlessly into space.

"You like it?" he said to Mort, in pretty much the same tone of voice people used when they said to St George, "You killed a what?"
Albert grunted. "Do you know what happens to lads who ask too many questions?"
(That was a cinematic trick adapted for print. Death wasn't talking to the princess. He was actually in his study, talking to Mort. But it was quite effective, wasn't it? It's probably called a fast dissolve, or a crosscut/zoom. Or something. An industry where the senior technician is called a Best Boy might call it anything.)
