Dæmonology

I'm reading the first book of the His Dark Materials trilogy (The Golden Compass or Northern Lights, depending where you live) and I've decided I really want need my own dæmon.

Wouldn't that totally freak out Gypsy and Cab?

I think I might be suffering from a Peter Pan complex though (but only insofar as His Dark Materials, right?). In Pullman's world, dæmons can change shape while their human counterparts are children. Once you grow up, your dæmon stays in one particular form.

If I had to grow up, I think a small dragon would be nice, about the size of a cocker spaniel. However, if its form represents a characteristic of my soul, lately it'd be no more than a theatre-going bookworm with a taste for martinis.

What would your dæmon be?
