Then they discovered, by the light of the lanterns they carried, that there the water had broken through, and made an entrance to a part of the mountain of which Peter knew nothing.

But they were hardly well into it, still following the light, before Curdie thought he recognized some of the passages he had so often gone through when he was watching the goblins.
After they had advanced a long way, with many turnings, now to the right, now to the left, all at once their eyes seemed to come suddenly to themselves, and they became aware that the light which they had taken to be a great way from them was in reality almost within reach of their hands.
The same instant it began to grow larger and thinner, the point of light grew dim as it spread, the greenness melted away, and in a moment or two, instead of the star, a dark, dark and yet luminous face was looking at them with living eyes.

And Curdie felt a great awe swell up in his heart, for he thought he had seen those eyes before.
'I see you know me, Curdie,' said a voice.
'If your eyes are you, ma'am, then I know you,' said Curdie.

'But I never saw your face before.' 'Yes, you have seen it, Curdie,' said the voice.

And with that the darkness of its complexion melted away, and down from the face dawned out the form that belonged to it, until at last Curdie and his father beheld a lady, beautiful exceedingly, dressed in something pale green, like velvet, over which her hair fell in cataracts of a rich golden colour.
