> 51st oblast russia has 48 oblasts, but not all russian territory is oblasts. they're not the same as states in the us. i doubt fingolia would fit into an oblast. more likely a krai or an okrug like the other uralic reindeer-herders (or a grand-duchy when the empire is restored). the word you are looking for is federal subject, of which there are 89. so fingolia would be nr. 90.
