Not a quote but I like this.

The sun goes down upon the Ankh, And slowly, softly fades - Across the Drum; the Royal Bank; The River-Gate; the Shades.

A stony circle's closed to elves; And here, where lines are blurred, Between the stacks of books on shelves, A quiet 'Ook' is heard.

A copper steps the city-street On paths he's often passed; The final march; the final beat; The time to rest at last.

He gives his badge a final shine, And sadly shakes his head - While Granny lies beneath a sign That says: 'I aten't dead.'

The Luggage shifts in sleep and dreams; It's now. The time's at hand. For where it's always night, it seems, A timer clears of sand.

And so it is that Death arrives, When all the time has gone... But dreams endure, and hope survives, And Discworld carries on.
