I didn't know about one of the Shadow faxes dying, but I do know that there were two Shadowfax horses. Names were Blanco and... oh darn it, I forgot. Haven't watched that part for over a month. It's a tragedy. Got to watch it again soon. What's even more interesting is that Ian McKellen didn't do the riding. It was somebody else, really good at riding. And it never says that Peter's unicorn doesn't talk! For shame, thinking that a unicorn doesn't talk. Tsk tsk. Oh, yes, it doesn make another mention of the flying horses, in the Last Battle, as they're going 'Further up and further in!' Polly and Digory say that they remember this place, and one of the animals says, 'Then it's true, that in the beginning of Time you two were taken this way by the father of flying horses?' or something like that.
