How does Queen Jadis behave when the pool takes them to the dark world? How does she describe it?

She told the children that the darkness wasn’t Charn and there was nothing in this world. She might think this place was horribel and she said “my doom has come upon me” .

What did the children hear in the darkness?

A voice had begun to sing, there were no words and hardly even a tune. Only a most beautiful noise

What "two wonders" happened in the same moment?

One was that the voice was suddenly joined by other voices; more voices than you could possibly count.

The second wonder was that the blackness overhead, all at once, was blazing with stars. One moment there had been nothing but darkness; next moment a thousand, thousand points of light leaped out

Who is the Singer? How is he described?

It was a Lion.  It was huge, shaggy and bright. It stood facing the sun and its mouth was wide open in song
