A coach rattled across the moorlands, many miles away from Lancre. From the way it bounced over the ruts, it was travelling light. But darkness came with it.

The horses were black, and so was the coach, except for the coat of arms on the doors. Each horse had a black plume between its ears; there was a black plume at each corner of the coach as well. Perhaps these caused the coach's strange effect of travelling shadow. It seemed to be dragging the night behind it.

On the top of the moor, where a few trees grew out of the rubble of a ruined building, it creaked to a halt.

The horses stood still, occasionally stamping a hoof or tossing their heads. The coachman sat hunched over the reins, waiting.

Four figures flew just above the clouds, in the silvery moonlight. By the sound of their conversation someone was annoyed, although the sharp unpleasant tone to the voice suggested that a better word might be 'vexed'.

'You let it get away!' This voice had a whine to it, the voice of a chronic complainer.

'It was wounded, Lacci.' This voice sounded conciliatory, parental, but with just a hint of a repressed desire to give the first voice a thick ear.

'I really hate those things. They're so... soppy!'

'Yes, dear. A symbol of a credulous past.'

'If I could burn like that I wouldn't skulk around just looking pretty. Why do they do it?'

'It must have been of use to them at one time, I suppose.'

'Then they're... what did you call them?'

'An evolutionary cul-de-sac, Lacci. A marooned survivor on the seas of progress.'

'Then I'm doing them a favour by killing them?'
