Greetings!
Ok, Joshua, I like your ideas. In fact, I've done the same. What follows is a rough outline of some details of my own campaign;
Elves
____________________________________________________
I only have three types of elves. I use High Elves, Wood Elves, and Drow Elves.
My High Elves have several different cultures. Loosely united, but distinctly different--culturally, rather than by hard-wired *stats* For example, I have the main High Elf kingdom situated on a large island-group. These elves are Celtic in culture. Druids are critical elements to the society, as are chariot-riding warriors.
The High-Elves to the far north, are very Nordic, with blends of Norman culture. Basicly Norse Vikings with the addition of huge stone castles. They use Druids as well, but there are some differences. The northern Druids are skilled in rune-magic, and there are sects of berzerker-priests. There are also several cults of blood-thirsty women druids that operate in the deep forests.
There is another High-Elf kingdom on the continent of Arathan. They are castle-dwelling, and highly focused on the sea. They have warships that have self-contained pools that hold sea-lions for additional combat support. These elves are very refined in manners, ettiquette, but also much involved with sea-born trade, as well as treaties with various human kingdoms. These elves are also very warlike, and proud.
Another High-Elf culture based in Arathan is very urbanised, with large cities, and high use of everyday magic. They are very sophisticated, but also decadent. They are undergoing a civil war between two factions. One faction, termed derisively as the "Human Faction" is in favor of increased treaties, and involvement with the Vallorean Empire, as well as various human barbarian tribes throughout the area. The other faction, called the "Traditionalists" are not only against the "Human Faction" by being more isolationist, but they also advocate enslaving various human barbarian tribes in the area, and infiltrating the Vallorean Empire with savage guerrilla-war campaigns, designed to roll back Vallorean expansion. This elven kingdom doesn't really have a navy, but they pride themselves on supreme integration of war-wizards, and heavily armoured elven knights.
Another High-Elven culture exists far to the south, and is a very different realm. It is ruled by an elven aristocracy, but has comprehensively integrated various black humans into society, and intermixing with these native humans on a large scale. In addition, they have blended Egyptian-like customs, and embraced a blend of elven and Egyptian-like religion. This elven kingdom also has intermixed with coffee-skinned, Pheonician-like humans. They have a huge navy, and extensive trade networks. These elves have packs of trained war-baboons, and a type of hornless, herbivorous dinosaur, somewhat larger than a rhino, that they use for cavalry. Here, no druids exist, but a powerful and ancient priesthood. Female priestesses are especially powerful, politically speaking. They have cities of marble, ivory, gold, and cedar.
Wood Elves exist primarily in the northern forests of Arathan, and they are more primitive in culture. They are different stat-wise from High Elves, though inter-breeding is possible. These Wood Elves are similar to Germanic barbarian tribes, and have prodigious armies of savage berzerker warriors, as well as archers, and they paint themselves, and have groups of powerful Druids that practice human-sacrifice on a limited basis. They also have groups of animal-totem Sorcerers that prowl the dark forests.
Drow Elves are similar to High Elves, however, they have been changed by centuries of living underground, and in other ways as well. Drow Elves have Deep-Earth kingdoms of sophisticated cities and fortresses, with sweeping architecture, and superior magical integration. They have also mated extensively with Demons, and have high populations of half-fiends.
A sub-branch of Drow Culture, is a surface-dwelling kingdom that has established a powerful kingdom in a vast rain-forest far to the south of the continent of Arathan. This rain-forest dwelling kingdom of Drow have also dominated and intermixed with a huge tribe of black humans, as well as introduced Demonic breeding. The resulting kingdom is a mix of African shamanism, and Drow religion. They have huge Ziggurats, and keep millions of slaves. They regularly practice human sacrifice, and employ Georgosaurus cavalry. (Essentially a smaller version of Tyrannosaurus Rex as cavalry) They have huge cities, and have arenas of gladiators to entertain the masses of screaming, blood-thirsty citizens. There are no stat differences, but differences in society, and religion. This Drow Kingdom is ruled by a king and queen, and have several orders of Necromancers serving the kingdom. They still have a female-dominated priesthood, but the religion contains male and female deities. The priesthood is composed of female Drow and half-Drow Clerics.
Dwarves
____________________________________________________
Dwarves are only one type, stat-wise. They primarily live in mountain-kingdoms based on a monarchy. However, there are also barbarian kingdoms of Dwarves that live in the far North. They have similarities with Northern Human barbarians, but they do have mountain homes, both underground, and in above ground fortress-cities. These Dwarves have berzerker-orders, rune-priests, as well as groups of skilled Rangers that patrol the cold forest frontiers of their domains. These Dwarves slaughter Orcs with no mercy, and also have had wars with the High-Elves, and humans alike.
More south, near the Vallorean Empire, the Dwarves have become increasingly sophisticated. They have extensive hallowed out realms in the deep-earth, and in the surface of the great mountains as well. They trade extensively with humans and elves alike.
____________________________________________________
I also have Pheonician-like Minotaurs, Elephant people that live in neatly organized herd-cities, where they live communally. I also have kingdoms of Hippo people that live to the south, and they have Egyptian-influanced cities. These are just some rough notes, though.
Semper Fidelis,
