Another Dragon , this one with deep blue scales and a yellow smooth underbelly landed with a lurch as it whipped its tail into a street cart filled with vegetables.

Blue Dragons generally prefer the Deserts of Kur and Chikara or any other dry area.  Tough skins and a modest layer of fat helps deal with wide deviations in temperature.
