The flat coast and river valleys of southern and central Ostrobothnia, from Kristinestad to the Pyhäjoki.
An Iron Age farming society flourished in the Kyrö river valley (Isokyrö) and at Vöyri until about the 9th century, when it vanished; Virrankoski thought it was destroyed (en.wikipedia Kvenland). In 1200 the land is a wilderness of rivers, bogs and a coast rising slowly out of the sea, used in summer and winter by hunters, fishers and traders from Satakunta and Tavastia, with Sami in the inland forests. Swedish settlers take the coast during the later Middle Ages and Finnish settlers from Savonia the inland, both long after 1200 (en.wikipedia Ostrobothnia).

What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.
- later Middle Ages (after this year)Swedish settlement of the coast; Finnish settlement inland.
Places of note
- Isokyrö: the Kyrö river valley, site of the earlier Iron Age settlement
- Lapua: the Lapua river
Where the sources disagree
Evidence: Archaeology of the earlier Iron Age settlement; no source for 1200.
On the map: Drawn as 'claimed' (seasonal use), from the Satakunta border to the Pyhäjoki, about 60 to 120 km inland. The inland edge against the Sami forests is a judgement.
