If I may inject my opinion here..
Man to me represents a mixture of the cultures of the British isles.
As has been said, there is the Isle of Man. But also, we can't forget the contribution of the longbow to the Hundred Years War, and how deadly that weapon made the English armies in that time period.
and of course King Arthur himself is supposedly interred on the isle of Avalon.
I believe Lord Warden was also a title in England. (or maybe still is

) A lot of similarities.
Pythium in my opinion is representative of the Eastern Roman Empire(BYZANTIUM). Both tried to (rather unsuccessfully) pick up the pieces of the greater fallen empire. Although Pythiums armies are a bit more traditional roman than the greek armies of the east, I think it is overall a good fit. On top of that, its nice to see the purple standard. Very Byzantine.
Maybe their priests could have been eunachs though. That'd be kinda neat.
Other than that the way I interpreted the nations to be are:
Abysia - not sure. HELL?
Atlantis - I guess Atlantis
Pythium - Byzantium with a pre-christian Rome element
Man - British
Ulm - medieval germans
C'tis - no idea
Arcosscephale - reminds me of ancient greece
Caelium - not sure. HEAVEN?
Ermor - Roman empire.. though maybe later Rome when it began using a lot of foreign mercenaries when manpower ran short. Replace undead with barbarians and it works out pretty well.
Marignon - reminds me a lot of inquisition era spain. It could nominally represent the papacy too, though I dont think they wield that sort of religious authority, it helps me fit them better into the disintegration of Ermor.
Pangaea - Not really sure. It is sorta mythological in a greek way. Not really a greek theme to it, but the creatures I remember from reading old greek myths, but they could be borrowed from wider mythology.
Vanheim - To be honest, with their ships and some of their units, they somewhat remind of me of the vikings. But I havent played with them enough to really make any firm judgement.
Jotunheim - I guess another scandanavian realm. But more related maybe to a mythological era. Someone before gave a good analysis of it, I'm not really too sharp on Scandanavian lore.
R'lyeh - Not sure.
Mictlan - Aztec empire , or at least mesoamerican.
T'ien Ch'i - some chinese or oriental empire. Kinda Ming dynastyish.
Machaka - Not really sure what these lads are, but since we don't have anyone yet from Africa I'll make it a african tribal state. That's my guess since thats what pops into my head when I hear "Witch doctor"
