The Rjurik are clearly based on a kind of Norse/Viking culture, but if one
goes through the published materials they are depicted as being war-like
not in the offensive, expansionistic way of the reaver period of such
peoples, but in defense of invasion of their homelands from various sources
like Anuirean empire, orog raiders and a few awnsheghlien.
Now, I know that might strike some folks as a little odd. Removing Viking
raiders from the culture that is often definitive of Vikings? It is a
little odd. However, if you consider that Anuireans are in many ways
crusaders without Christianity, the Khinasi are African/Arabs without
Islam, Cerilian elves are immortal and halflings have an intimate
relationship with the campaign`s nether world then portraying the Rjurik as
warriors who focus upon self-defense rather than raiding makes a little
more sense. The portrayal of the Rjurik is not meant to be a 1:1
recreation of the historical cultures upon which they are based. It`s a
fantasy fictionalized version.
Having said that, there are a few rationalizations that one could come up
with for how/why the Rjurik would have developed as they did as opposed to
their real world amalgams. For instance, population size among the Rjurik
never reached the kind of size that is necessary to foster an expansionist
movement. (The Vikings for all that the gory details regarding raids is
emphasized really were more of a cultural/population expansion then just a
military one.) Also the Rjurik are set upon by more internal foes than
were their historical counterparts in the form of awnsheghlien and other
hostile races. Such a condition does not for an expansion into nearby
realms make.
Lastly, the cultural basis of the Rjurik is strongly on a nomadic "live in
harmony with nature" fantasy native American ideal. (Personally, I don`t
think that idea ever really existed as much more than a propaganda and
post-colonial reinterpretation, but that`s no reason not to employ it in a
fantasy campaign setting.) That emphasis is definitively not expansionist
and nearly pacifistic in its portray, so culturally it would oppose the
kind of raiding party development that the Viking reaver period
represented–which was mostly about the acquisition of wealth. So on the
whole this is one of those basic differences between the real culture(s)
and the fantasy portrayal of them that is so common in gaming and, I`d
suggest, perhaps even more definitive of BR than other settings.
Now, that`s not to say, of course, that there would be absolutely no Rjurik
raiders of the Viking type, nor that their ability to build ships of their
own culture should somehow be dependant upon having massive
shipyards. Rjurik culture is divided and it is sensible that amongst the
more “developed” and populated regions of the Highlands that a few bands of
raiders might spring up. There is also the general expansion of the Rjurik
by sea into Thaele which, of course, takes some serious shipbuilding to
accomplish.
