And the eastern isle from Ahma I'll call, starting from the north,
Pohja,
Itä,
Etä and
Lounas, which translate to "Bottom" (from which the word "pohjoinen", north is derived), "east", "far (away)" (from which etelä, "south" is derived), and "lounas", which is the actual name for south-west.
Finnish has individual names for EIGHT cardinal points on the compass - though it seems no one remembers the order for the intermediate points. Starting from north, moving clockwise, they are: pohjoinen, koillinen, itä, kaakko, etelä, lounas, länsi, luode. Which, I hear is pretty unique.
EDIT:
And while I'm at it, I'm giving names to the land-masses, too!
Left to right,
Myritiä, Vertanttia, Eiskaja, Anivonttia, and
Kotosaaret.
The river in Eiskaja is obviously
Jakojoki. The island south of Vertanttia is
Mousari, and the easternmost island in Anivonttia is
Tammila.
Ach, I'm naming the islands west of my realm!
North to south,
Piensaari, Suursaari, Siniviiri, Punaviiri, Viherviiri and
Keltaviiri.
