I asked Steve how big the planet was (for the mapping project) and he said, "I use 'roughly Earth' for convenience." >From Dzur Mountain (which is about as far north as any jungle or other tropical condition is attributed) to the North Sea north of Fenario (Brokedown Palace describes the bitter cold of the north sea) appears to be about 2,800 miles, and if the planet is the same size as the Earth, that works out to be about 41 degrees of latitude between the tropics and the arctic. That puts Dzur Mountain at approximately 45-(41/2)= 24.5 degrees latitude, which is very close to the Earth's tropical extent of 23.5 degrees, which, at least on the Earth, is due to the tilt (that is, the Earth is tilted at 23.5 degrees, which marks the northernmost/southernmost latitude which ever bears the full brunt of the sun). Of course, the two big problems with the above are, 1. It's based on my work on release 2 of the map of Dragaera, which is not yet published. 2. I am nearly convinced that the Enclouding moderates (or at least affects) the weather within the Empire.
