As a Finn who has gained as much out of Finland's history as possible without being in a university, I wish to share information on iron age Baltic Finn tribes. I know for certain that none of the tribes of the area will be a faction in the game, but this information should at least help, when designing the region.
First off, there's this article on Baltic Finn tribes (with the exception of Votes, Ingrians, Veps, Estonians and Livonians) in Viking ages.

written by Kristian Ola aka. Wilpuri (while possible that this is the same Wilpuri that is at TWC, I am unable to find out if it is actually him)
(also the images happen to be broken for some reason)
The article takes a look to the 3 major tribes of Finland, Sums/proper Finns, Jems/Tavastians and Karelians. It also talks of the Kvens and Bjarmians, which according to the text, were not actual tribes, but rather groups of hunters, traders and merchants. Hill forts (including the hillfort of Rapola), weapons and warfare are also mentioned.
Secondly there is this map, showing the rough regions of the tribes, and locations for cemetaries and major settlements. For some reason the map forgets the Ingrians though (which would be in the St.Petersburg area, between Karelian and Vote territory)
I hope that this all is of use to the team.
Cheers.
