I think that I would want to invite creatures over, since I'm fascinated by the idea of them.
1. Reepicheep- I'm sure he has many interesting stories and he would just be so fun to be with
2. Glenstorm- He's very wise and I would want to study the centaur life
3. Dryad- same reason as Glenstorm, to understand the dryad life

Good topic!

1 Aslan - need I say more?

2 King Lune - seems like a vary fun and jolly person.

3 Reepicheep - Because he's Reepicheep!

Ooh, good idea for a thread.

1. Professor Kirke. I love his ideas and philosophical views; I'd really enjoy talking to him.
2. Father Time. So many questions I would like to ask! I want to know all about the civilization he once ruled as king in Narnia.
3. The Hermit of the Southern March. He lived for such a long time and must have seen so many interesting sights in his pool.

The only problem with having them all over for tea is that I would probably be so intimidated by their years and knowledge and wisdom, I wouldn't be able to say anything.
