'The grey hours are upon us,' she whispered, gently shaking his shoulder.

The fire burned low in the gray hour before dawn.

Wait here until the grey hours herald the new morning.

Dawn had broken, pushing the grey hours before it.

We had better be on our way, before the grey hours herald another dawn.

'The grey hours have come,' she whispered without hope.

The grey hours are upon us and I am still none the wiser which path to take.

The grey hours had come, spreading cold mist between the close, crowding trees on either side of the road.

In that gray predawn hour every symptom of aging was more acute.

Beasts came down to drink in the gray hour.
