This was a game we had on the old forum that I've kind of forgotten about. It's a super-simple game and it runs something like this. You offer any two Narnia characters. The next person answers with his/her favourite of the two and pairs that name with any other character for the next person to answer. The third person does the same and so on.
For example....

person 1: Polly or Susan?
person 2: Polly or Digory?
person 3: Digory or Glimfeather?

So with that I'll ask:
Digory or Glimfeather?
