If you like you can look at the (sketchy, incomplete) GM notes as well.

Fashion

Vegdarbarra: Primarily Siberian, Siberia being the archetypal frozen wasteland of lonely villages with the occasional outpost of a vast military force that has fallen into disrepair.

Lasinia: Amongst exiled aristocrats and those nostalgic for the old regime, Greco-Roman influences abound, although at the time of the revolution Lasinia was much more technically advanced than Rome during the Classical period - the late Byzantine period, with its Greco-Roman origins having developed in a decidedly non-togas-and-sandals direction over the years, could provide a good starting point. The revolutionary Soviet government is seeking to expunge all traces of the old aristocratic culture from Lasinia: it favours simple, non-ostentatious clothes, large black coats being very much in fashion. Anything from 16th century Puritan garb to Lenin-era Russian dress is appropriate.

Irgar: Generic Nordic influences mostly, with perhaps a few Celtic themes here and there.

Jurica: Mainly Arabic/Persian, with Indian influences in the more fertile regions.

Horizon: A real cultural mess. Influences from the other Four Nations meet everything from the Elizabethan to the Victorian era (with the very occasional early 20th century influence creeping in). The lower classes tend to dress like working class folk from the 1800s; the aristocracy are very much into wigs, ruffs, tights, the whole Blackadder II deal, especially for formal occasions. Merchants and factory overlords tend to look like 19th century sweatshop bosses. Government bureaucrats dress like Sam Lowry's workmates in Brazil. In the criminal underground and related subcultures - ie, the sort of circles the player characters knock about in - people tend to mix-and-match influences wildly, since their wardrobes tend to consist of whatever high-quality clothes have "fallen off the back of a cart" lately.
