1. What should we know about the apples of immortality?
They cannot be safely picked or consumed except at Aslan's own personal instruction. Any who try under other circumstances will find the results more unwelcome than otherwise.

2. What is Winter's problem?
It isn't my business to say.

3. Are there more surprises in Narnia like the dark tunnels?
Not presently.

4. Did Winter omit anything when he marked the tunnels?
You will find his map entirely sufficient to your purposes.

5. Why couldn't Winter go back to Earth?
The way was not open to him.

6. Is there a way to let him die?
No, and nothing like it.

7. Is there in general a reliable way to get between Earth and Narnia and back?
Not that you would call truly reliable.

8. Are there any magic items lying around we could get without having to wait for you to bring them?
You have the means to find out. Enjoy your search.

9. What other questions might it be worthwhile to ask you and what are the answers to them?
It is not in my nature to be an oracle.
