Temeraire gains his full growth and maturity when his Ruff and whiskers grow in which makes him even less like the other British Dragons and causes him to become a bit more lacking in self-confidence. But his speed and agility is noted and at one point Laurence clockes him as traveling twenty-five knots. But Edward Howe sends Temeraire a book of Chinese stories translated into English and on the cover is a picture of the Yellow Emperor, a Celestial Dragon that looks just like Temeraire.
