The whole autumnal themes of the books sets the framework for the northern air feel for me. Especially so in my primary world, in the winter, when the angle of the sun is such that the light becomes bent, and confirms my place in the northern hemisphere. Something in my gut wants to reach for my war hammer and drive my ship to new lands..... ahhiiiiiaaaahh-ah!
only after the carefull reading of chicken organs, of course
seriously though, it's the lighting for me.
