Ah, you see, so much to think of, and I only started last Friday. I noticed one dragon in the mandatory stock which had some spikes near its beak, which made me think of holders for the firestone sacks. I tried to fit a rider on one of the dragons but had trouble to manipulate it in a natural pose, (if you can consider riding a dragon natural
)
It was some 10-12 years ago when I read those stories, so I forgot what the tread actually looked like, I had clouds of red, whirly rain-like stuff in mind, but you're right, it was more like silver. It remember the red star had something to do with it.
I really need to re-read the books again!
Do you know the novels by Robin Hobb? Those are ones that once you've finished them let you have trouble adjusting to the normal world again... I would not suggest to read part 2 of the Soldier Son Trilogy when you want to loose some weight, at least I gained some when reading it...
