‘Unless the king should come again?’ said Gandalf. 'Well, my lord Steward, it is your task to keep some kingdom still against that event, which few now look to see.

But all worthy things that are in peril as the world now stands, those are my care. And for my part, I shall not wholly fail of my task, though Gondor should perish, if anything passes through this night that can still grow fair or bear fruit and flower again in days to come. For I also am a steward. Did you not know?’ And with that he turned and strode from the hall with Pippin running at his side.
