Mark: Do you want my opinion? Well, I'll give it even if you don't, 'cause that's the kind of troublemaker I am
A gryphon/griffon, if it were a magical creature, should be able to communicate mind to mind, in a similar manner as dragons in many stories do.
If it is just a beast, then its brain and beak would not allow it the power of speech as we know it.
Balinor - did you read Mercedes Lackey's White Gryphon and the rest? They are good stories. In fact, my first online user name came from one of her characters in Black Gryphon.
