Here are a very few of the Hundred; these are city-states of greater or lesser power. Some, like Simblios, are hegemons who rule in all but name much of the surrounding area and surrounding cities. Others, like Peklichr, are powerful on their own.
Xhiklus
The legendary Metal City, Xhiklus lies at the nexus of a great network of railways amidst the Oxhidaizen Plains. Xhiklus is an ancient city, and has the distinction of having been constructed entirely of metal, at least for the most part. The elder districts of the city are known as being among the most beautiful and strange architecture in the world, while the New Districts (those not constructed from iron) are known to be incredibly populous, and a place to find any product imaginable. A large part of the workforce of Xhiklus is occupied in keeping the Iron Districts clean, shiny, and free of rust, which is a constant job.
Xhiklus maintains a large standing army which answers directly to the Diktator of Xhiklus. A new Diktator is elected every ten years by the army, and is generally chosen from the ranks of the High Kommanders, though there are several instances of influential civilians being chosen.
Peklichr
Peklichr lies on the coast of the Heavy Sea, with the rugged Pangloss Mountains above it, and has grown fat off the bounties brought it by trade. Peklichr is connected by the Heavy Sea to the rich states of Mehmoriumh and Rehmnisenz on the opposite coast. Peklichr is known for it's vast industrial sector, and is often called the Smoky City for the clouds of smog and ash which roll across the skyline. Peklichr, in it's far past (roughly a thousand years ago), was once a city in the Ugromantic Dominion, and still retains in it's architecture and (somewhat) in it's language traces of those ancient people and the worship of their strange pagan gods.
Peklichr is ruled by an oligarchic Council of Eleven. Each Councilor sits on the Council for a life term, or until they resign. At some point during their term (generally near the end, though there is no set time), a Councilor designates an heir to take their seat on the Council. Peklichr's Council is highly elitist, and there have been only a very, very few Councilors in it's history which were not of the city's upper classes.
Simblios
As ancient, if not older, than Xhiklus, Simblios is known far and wide for it's incredibly intricate, baroque, and ancient architecture, it's monumental towers and fortresses, and it's huge size. Lying on the great Thadar River (which flows into the Black Gulf), Simblios has the huge and fertile farmlands of the Tar Epar Van to the north, the swamps of Shavpek on the south, and the Black Gulf and Mr. Krahn's Sea on the east. It is also known for it's crime, it's pollution, it's Byzantine corruption, and the despotic, immortal rule of the Emperor of Simblios, a man who has held the title for 400 years. Simblios is the largest of all the cities of the Hundred, and it's influence matches it's size- it is the leader of a hegemony of satrapies, client states, "advised" cities, nations "indefinitely occupied", and a host of states so frightened of the vast power of Simblios and it's truly awe-inspiring army that they follow it like a flock of frightened sheep. In all but governmental acknowledgement, this is the Simblian Empire, and most cartographers note it as so, though officially, there is no such country.
Simblios maintains a vast, powerful, and highly advanced army, including a war-fleet, an air-navy, and numerous small mercenary groups kept on constant payroll. Simblios is always working on the "next big project", and espionage from other states into Simblios frequently involves the crippling or halting of the Empire's next secret weapon or great ritual.
Ala Spirult
This young city lies within the Spirult Valley, amidst the vast Towering Forest. Ala Spirult gained it's industrial technologies and factory functionality largely through underground dealings with Mundrung, with which it maintains a cordial relationship. Ala Spirult has very little in the way of monumental or beautiful architecture- it is a well-planned, clean, neat, but uninspiring town, with an industrious, hard-working populace. Ala Spirult is know for having the finest trainyards north of the Pangloss Mountains.
Ala Spirult is ruled by the Democratic Council, a group of 40 representatives (one from each neighborhood of Ala Spirult) who meet twice a year to produce laws.
Mundrung
Mundrung lies in the cradle of the north, amidst dark, chilly pine forests, where the sky is always overcast, and the craggy mountains roil with mist. Mundrung is a large city (it is often fancied "the Giant of the North") who's culture is a synthesis of old and new- much of Mundrung's populace is part of the Anteknophelii, a philosophical movement which rejects much of the technology and machina of the world. Thus, Mundrung is home to both huge timber halls and great clockwork towers, bearded mountain men and goggled alchemists, and has a reputation as a wild and somewhat lawless city. Mundrung is the unofficial leader of a small group of northern states, and has the largest rail network of any of them (though in the lawless north, train robberies are a frequent problem).
Mundrung is currently ruled by King Agrul II of the House of Viblust. The Viblust Dynasty has ruled Mundrung for a very long time, and many anticipate that, as Agrul still has not produced an heir with his chill and fruitless wife (a woman of the South), he will be the last of them.
