The planet of January is tidally locked, one side endless, blazing daylight, and the other endless, frozen night. There are two human cities on January, in the narrow temperate zone. They're cities of very different cultures.
Xiosphant is rigidly autocratic, with very tight rules governing waking, sleeping, work, the limited amount of leisure time available. The language is complex, with case forms that indicate social rank of speaker and of the person addressed, time of day, and numerous other details.
Argelo superficially appears to be without rules, and in reality is run by several Mafia-like families, and its own complex social conventions. There are no rules about when you can eat, work, or sleep, and the language lacks all the complex case forms, working entirely by word-order.
