Quote from : A Deepness in the Sky Book

It is an edged cliché that the world is most pleasant in the years of a Waning Sun. It is true that the weather is not so driven, that everywhere there is a sense of slowing down, and most places experience a few years where the summers do not burn and the winters are not yet overly fierce. It is the classic time of romance. It's a time that seductively beckons higher creatures to relax, postpone. It's the last chance to prepare for the end of the world.
