[@Lovejoy] I figure there's the stormy season -- that's winter.  Bitter cold, blizzards, etc.  Long nights, that sort of thing.  And then summer is more "the warm(er) season".  I'm going off of the concept of a rainy season and a dry season, like in deserts, only with the cold and lots of snow being an issue.

Although actually if it's cold enough snow doesn't form!  But we can totally handwave that.  Alternatively, there can be the first stormy season, the dark season, the second stormy season, and the warm season, where storms happen when it's cold but not TOO cold -- so spring and autumn.  Warm season is still summer, and dark season is based off of the longer nights.  Although I am sure that axial tilt is far less related to the changing temperatures here, or that it would at least work very differently.

I think drawing solid parallels to earth and the world we players are familiar with helps keep things grounded.  Yeah, the odds are low, and it's fun to come up with some complicated system.  But it's not really necessary for enjoyment, and this serves to help us keep things straight.  Seven day weeks, twelve months in a year.  Sun rises in the east, stuff like that.  I've played with multiple moons in my writing, but that would in turn affect the way locals marked the passage of time, if you think about it.  Of course you don't /have/ to...but I often like to.  ^.^;;

Then again, I don't know if these guys can see a moon, so...I know there's no stars, so the concept is somehting from pictures and stories, most likely.  Is there a moon?
