“The Death of the Disc was a traditionalist who prided himself on his personal service and spent most of the time being depressed because this was not appreciated. He would point out that no one feared death itself, just pain and separation and oblivion, and that it was quite unreasonable to take against someone just because he had empty eye sockets and a quiet pride in his work. He still used a scythe, he'd point out, while the Deaths of other worlds had long ago invested in combine harvesters.”

― Terry Pratchett, The Shepherd's Crown

“He created me. Quis custodiet ipsos custodes? Who watches the watchmen? Me. I watch him. Always.”
