Founded thousands of years ago Aerie is one of of four floating rocks, all that remains of the sky continent of Netheril. Using arcane magic that has since been lost (though some speculate on that point), the floating Islands were all that remained of the destruction of the former large landmass that floated in the air. Today, the various sky cities have established strong trade corridors between the cities and through the various other communities in the sky. Magic is accepted as a way of life, but it's practice is discouraged except for among the elite. Many practitioners of magic who grew up in the cities have turned to the council for support or have struck out on their own. In recent times however they have turned to technology, and are the industrial powerhouse of the sky.

Aviary consists of three linked floating rocks. Being the breadbasket of the floating lands, crops like wheat and corn are grown extensively, along with orchards of fruit trees. Mining is also done here, but so as not to disturb the agricultural production is all done underground. Well constructed roadways line the interior of the cities.

A glittering jewel of the clouds, Blue Sky is a political, economic, and military hub of the cloud realms. The city commands few resources of its own. In fact, the cloud realm is barely large enough to accommodate much more than the city. As the seasonal winds blow, cloud realms drift across the sky. While the general wind patterns make possible rough predictions of a particular cloud’s location, the vagaries of the weather and the exact location of a given realm make trade difficult. Blue Sky is one of the very few exceptions to this general rule. Floating high in the atmosphere, it follows the same path year after year. Some sages believe Blue Sky is blessed by the gods to adhere to its course. Blue Sky's predictable location makes it the ideal trading centre for all the sky realms. As it moves through different regions of the sky, traders swarm from across the air lanes to meet at the city, sell their wares, and load up cargoes of worked goods and raw materials that are rare in their home realms. While some traders may deal with other cloud realms, most lack the resources and interest to track down settlements as they drift across the sky. Blue Sky’s status as the preeminent trading port of the sky ensures that a merchant can find a market for his goods and a wide range of products to carry back home. It contains ruins, and what looks like landing pads, as well as underground dwellings, but they have appeared abandoned for several thousand years, no markings on the wall survive, resulting in the ruins leaving no clue as to the place.

Sky City is a completely man-made aerial scientific colony of a few thousand workers and support staff hovering over the North Pacific Ocean. 36,000 repulsorlift engines and tractor beam generators kept the giant city floating above the planet. It contains 392 levels, along with platforms and rooms for residents and visitors. The top 50 levels of the city are used for scientific research, while the lower levels are used for accommodation. Generators on the underside of the city emitted tractor beams that converged below the reactor bulb, creating a funnel of energy that suspend the city in the air. The main saucer-shaped city structure is 16.2 kilometres in diameter, and 17.3 kilometres tall.

Star City 16 makes use of reverse engineered alien technology, combining a thrust-driving principle with artificially reversed gravity. All incoming and outgoing flights by air craft is done via the runway on top. There are hangars surrounding this section. The Star City has taken important precautions against storms and violent rainfall, lightning, etc. Lightning conductors can be projected through roofs of the tallest buildings in the city.

According to legend, this cloud realm is the centre of sky elf civilization and the first realm the elves civilized when they came to the clouds. It is made up of two linked continents both of which are rich lands. In the southwest it is sunny and temperate with prosperous farmland and pastures. The southeast is much the same if not more densely populated because of it’s rich farmland. The northeast and mountainous northwest are wild and cold and only sparsely populated. This however affords many of the countries wizards much privacy and so the land of the northeast is dotted with their towers or summer villas for the nobles that require more luxurious privacy. The central regions are thick with deep forests littered with dangerous beasts and monsters, many of whom are the result of some evil wizards experiment for it is here that those that require the most privacy to conduct their wild experiments come. Birds form a prominent part of Starmount; as mounts, pets, friends, familiars, and food. Many breeds are raised. Here is a partial list:
-Azure Eagles are a larger breed of giant eagle developed here by the Sky Knights as a mount.
-Tengali Pigeons are used for messengers, as they function as homing pigeons. They are a common sight, and harming one is against the law.
-Dream Owls come from some unknown world, and quite rare. They are sentinet owls capable of speech, and are much sought after by wizards.
-Whitehawks are friendly birds of prey and are bonded to children (of richer nobles), and seek to defend or seek help for their charges.

Stratos is second only to Starmount in size. Individuals with the ability to cast magical spells are automatically considered nobility and given the rank of aristocrat, regardless of their skill at spellcasting. Only aristocrats may attain the noble rank of Lord. People without the ability to cast magical spells are called "commoners" and can at best attain the rank of gentry or, at worst, the ranks of servants or slaves. Stratos is ruled by an Emperor or Empress who is advised by a Council of Wizards. It was formed from the amalgamation of several floating isles, which were moved together, and as the city slowly grew more islands were merged into the complex. To further compound the city mining parties on the surface plus resources mined from other floating islands. The city as it floats in the sky is large, with armoured walls to help fight off raiders. The city is divided into two levels the upper city starts at what is considered street level and goes up to the tops of the tallest skyscrapers where the elite of the city rule. The second part of the city starts at street level and goes down deep into the bowels of city. This underworld as it is known is inhabited by the poor, new immigrants to the city (unless they are wealthy), criminals and other unsavoury elements.
While the upper city is open with balconies every where and green plans, the under cities is always bathed in artificial light, and people may go months without having to venture up to street level. The under city is considered the lowest of the low region of the city, and consists of a network of girders, and small buildings that hang over open sky, with the city above. This part of the city is notorious for raider gangs to conceal themselves, and as a site for murder, as the bodies can easily be disposed of. it is also here that concealed docking bays and warehouses for black market dealings can be found.
