Certo

Very good! Although I must admit I panicked a bit when I first saw the thumbnail; I didn't realise that Certo had his wings folded down beside his legs, and I just went "Oh god, another Wyvern! NOOOOOOO!"

(...for the record, I hate it when films adapt dragons to film and turn them into wyverns because it's more likely that they would have evolved that way on a planet full of four-limbed creatures...personally, I think when you've got a gigantic fire-breathing reptile that's able to fly, you can argue that they might not need to follow that example...)
