It's a great big world out there. These are the highlights. This page will likely be updated often, so it's a good idea to check it frequently.

Name: Aquitaine
Similar to: France/Austria
Government: Imperialist. The motto of the Empire is "if we don't rule you yet, we're working on it."
Religion: Polytheistic. They like to think they're beyond that, though. Religion is for peasants.
People: Though they tend to be light-skinned, there is no one type amongst them. Darker-skinned people and mixed races are more common, due to Aquitaine's close relationship with Galimor.
Anything Else: Aquitaine's gotten a lousy rep in g-me, what with all the corruption and the conquering, but honestly, it's not all that bad working for the folks with all the money and all the power. The major unit of currency in-g-me is the Aquitainean soliel. The Imperial flag is a black eagle on a red field.

Name: Cecilia
Similar to: Italy
Government: Province of Aquitaine. Their current "ruler" is the Viceroy Alstanzo, who is an utter fruitcake. Naturally, he is universally adored.
Religion: Polytheistic. Sorta. They are an offshoot of the Assemblage who believe that all living creatures possess virtues worthy of emulation. Therefore you get small shrines everywhere to things like Saint Cow and Saint Fish.
People: Fair or lightly olive-skinned, usually with butter-blond hair and light-coloured eyes, although that's almost a stereotype. In reality, they range all over.
Anything Else:

Name: Drunnandannon
Similar to: Nordic/Icelandic
Government: Chiefdom. Individual clans consisting of both immediate family and extended kin are ruled by a patriarch who negotiates with other patriarchs in order to maintain the peace. The "king" of Drunnandannon, Knogrimmorrian, is simply the man who maintains the largest clan (and who can, if necessary, fight his way to the top).
Religion: Atheistic, with some aspects of ancestor veneration. As a rule the dwarves do not believe in anything they cannot see.
People: The dwarves (who refer to themselves as the Drüfan, or "family") are shorter than the Tuatha, but much stockier. Men and women alike grow beards. They range from blonds to redheads, and generally have blue or pale green eyes. They live for around three hundred years, with children tending to live with their parents until around the age of fifty. They also mate for life; widowers do not remarry.
Anything Else: Technologically, the Dwarves have got it going on. Consider them as possessing Da Vinci's scetchbooks and tweaking every single idea until it works. Drunnandannon, while extremely rich by most countries' standards, have an near-disdain for precious metals and jewels but will trade for wood eagerly. The standard of the current Dwarven king is a simple white banner with his clan's glyph in red.

Name: Erins Isles (Seelie Court)
Similar to: Ireland/Wales
Government: Feudalism. In theory, each of the three major islands has a ruling chieftainess who answers directly to the Queen Herself.
Religion: To paraphrase Terry Pratchett, it's probably wrong to say that the Tuatha believe in gods; it would be like believing in the postman. They have a number of gods and goddesses for whom they occasionally show appreciation by lighting big fires on hilltops or pouring out cups of wine before battles, but they do not worship the gods per se. They have no souls and do not believe in an afterlife. The Tuatha also have a long-standing neutrality with Hell.
People: The Tuatha top out at around five feet. They are dark in complexion, and their hair is either dark brown or dark red. They mostly have grey eyes, although an occasional genetic abnormality pops up once in a while for green eyes (considered bad luck). They have long tapering ears. The Tuatha are rather hedgy when it comes to admitting just how long their lifespans are, but it is known that the current Queen is over five hundred years old.
Anything Else: Anyone who is not a Tuatha is "tallfolk", even the dwarves (who are physically shorter than they are). Like the dwarves, the Tuatha tend only to value precious metals and stones for their decorative value--they like shiny things--and are more likely to trade for things such as textiles, building material, and luxury items from the Mainland. Tuatha have no capacity for drunkness (with human alcohol; on their own brews they get shitfaced), and are highly tolerant of both human poisons and human medicines, neither of which have much effect on them. They are all deathly allergic to iron.

Name: Eurastad
Similar to: Germany
Government: Monarchy, run by Andrew von Schwarzburg, but is in fact really run by the king's resident Red Witch. This is not really a secret, as it is well-known that all three of the von Scwarzburg's are off their rockers. There is also a High Elder Council... but they're more for show than anything else.
Religion: Montheistic--they believe in Elo (essentially, God) and worship him in all things. Their religion preaches a life of refusing oneself pleasure in this world in order to be more worthy of it in the next. It also preaches that redheads bear sin. There are hints that the worship of Elo is fairly recent as far as history goes and before that they worshipped a High Goddess and her Consort.
People: Generally fair-skinned, fair-haired, blue-eyed. Every hundreth person or so is born a redhead. Now and then you get dark eyes.
Anything Else:

Name: Lorrain
Similar to: Normandy/England
Government: Between revolutions.
Religion: Varied. The largest major religion worships the Blessed Assemblage, which falls somewhere between ancestor veneration and praying to the Catholic saints. Devotions to the deceased allow the dead to work their way up more quickly into the godlike Assemblage.
People: Tend to be fair or ruddy in complexion. Beyond that, anything goes.
Anything Else:

Name: Mercer
Similar to: Calais
Government: Imperial, under Aquitainian rule, with a few drawbacks. Mercer has swapped hands between Lorrain and Aquitaine for centuries now. Most of the inhabitants consider themselves Aquitainean subjects.
Religion: Like Aquitaine.
People: Likewise like Aquitaine, although Gali do not often reach as far as Mercer.
Anything else: Just call them Aquitaine Lite.

Name: Mittestadt
Similar to: Bavaria
Government: The ruler is Archduke Aernaut. He, however, is sort of a cross between Mad-Eye Moody and the Heir to the Grail Bloodline from Preacher-- paranoid, stupid, and a bit loopy. Very ill-tempered. The country is really run by General Gerhardt Geller, who is the head of the military.
Religion: Polytheistic but very steeped in ritual like Catholicism. Has a Mother Goddess and a Father God.
People: People are generally Aryan in appearance, with light to medium skin tones and light blond to medium brown hair, with blue or gray eyes.

Name: Qa'shydl (Kay-shee-DEEL)
Similar to: Moorish Spain
Government: Legally, Qa'shydl is a province of Aquitaine. In practice, they are an oligarchic theocracy wherein individual ora (singular or), or prophet priests, serve as interpreters of the holy law.
Religion: Monotheistic. They believe they are the original inhabitants of the world and worship a father-god.
People: Most notable amongst outsiders for being giants, the Qa'ad (ky-ED) tend to be about seven feet tall but can grow as high as nine feet. They range in complexion from sandstone-red to black-brown. Thick, black curly hair and dark brown eyes.
Anything Else: The longest-lived of the mainland peoples, it is not unusual for them to live up to a hundred-fifty years or for women to give birth well into their sixties.

Name: The Wreath Islands
Similar to: the Spanish Caribbean
Government: Nominally ruled by Aquitaine, and a port for many Aquitainean ships, the Wreath Islands have by now had so many flags stuck into them that no one knows, or indeed cares, who rules them.
Religions: Various
People: As a jumping-off point between Cecilia, Galimor, Qa'shydl, and Aquitaine, the Wreath's people are a mix of any or all of these types.
Anything Else:
