The air is made of dragons

DRAGON

Silvery serpentine air spirits. Arrogant, powerful, knowledgeable, inscrutable.
Loves speed, victory, freedom.
Wants: heat and magic items to devour, to show its strength and dominance, to be sovereign, SPEED!

Dragons have kinship with air and fire; they throne as Lords of the Middle Air among the clouds. Their bodies are serpentine and subtle; swift coils of feather, scale, fur and talon. No wings; they swim in the air as if in water. Their areal nature makes them hard to see. Only a silver shimmering, faster than thought, is what an untrained mortal may see of a dragon. 

Dragons are of air, and air is of dragons. Every breeze and zephyr is governed by a minor dragon. The Cardinal Lords govern the winds of the cardinal directions.

The Lords of the Middle Air meddle mostly in their own affairs, which are incomprehensible to mortals and have much to do with movement. Their parliaments scheme and battle amongst themselves up there in the sky. It can be cramped up there in the Middle Air; there's many a seething mess of coiling dragons whizzing around, as if in constant dance and constant battle. Movement is to dragons what territory is to mortals. They compete for speed and power. They race around the entire sky. They fight terrifying duels over cloud formations and pillars of rising heat. They court each other in break-neck race-like dances, whizzing by mountains. Salori legends say they chase the sun around the sky.

Dragons have infinite life spans and are nigh unkillable. Young dragons die if they stop moving - like the wind, falling still means that they simply become air - older ones just don't like it. If a dragon dies, its subtle body melts into clean air within hours. They know much - the air flows everywhere - especially about spiritual and cosmological matters and shifts. Dealings between dragons and mortals are exceedingly rare; for a dragon to deign to slow its all-important speed and listen to a mortal, the mortal must either be in possession of something a dragon wants (heat, mainly, or energy in other forms, such as magic or magical artifacts that they eat and consume) or very, very interesting. 

Talking to a dragon:
They won't, usually. Dragons only speak to those they respect. You could have a very long and personal feud with a dragon without it ever speaking a word to you.

By Estevao Teuber Pereirra

An audience with a dragon:

It is very worthwile to speak with a dragon - the true dragons of the air never lie, unlike the false dragons, the wyrms of the earth.

It's usually best to go to a hilltop or mountaintop for this. A dragon might come if you simply call for a dragon; but if you call one by name it is much more likely. Then the real trouble begins. The dragon will be there, slowly circling you, or slowly coiling around while it hangs in the air before you, its great predator eyes gazing at you. Make a fear save or a panic save or a morale save or what have you.
If you manage to swallow the terror, you, of course, probably don't speak the True Speech or Draconic or the like. If you can get beyond that, you may ask your question. The dragon may regard you mysteriously and take off; this is what usually happens. It might try to eat you. For a dragon to not just listen, but answer as well, is exceptionally rare.
The voice of a dragon sounds like the hissing of a cat, but enormous, or like gigantic cymbals. It shatters glass in a massive radius. Make another fear save. If a dragon answers someone, they will answer him every time. Such a person, the one dragons deign to speak with, is called a Dragonlord. It is not totally clear what determines who may be a Dragonlord; it's likely your PC's aren't, but it's worth a shot. Otherwise they'll have to find or hire a Dragonlord. 

Legends say it is possible to befriend a dragon, or the dragons. Little is known of how that would work. The minds and lives of dragons are so alien to mortals - governed as they are by the crushing cold of the higher regions, the landscape rushing below, the fights for dominance with talon and tooth, and always, always the terrifying speed. They live lives of solitude, struggle, and the purity and elegance of empty air - they value strength of character, obsessiveness, and ruthlessness.

How do adventurers run into them?
1. A dragon has installed itself as the dragon-king of a local village or city; it brings rain for the crops and is really quite charming, but eats people as tribute.
2. A dragon, wounded in the great fights in the Middle Air, has crashlanded right into the city/village/ship that the players are in. It is wounded but still very dangerous. Make a powerful dragon friend or finish him off?
3. A mage has gained control of a dragon somehow. He is using it for evil; kill it or rescue it?
4. The players run into a dragon while climbing a mountain.
5. A dragon emissary from the Warring Parliaments of the Middle Air contact the players due to a great, potentially apocalyptic threat. If the dragons come to you, there's a serious problem.

A dragon and his friend. By Perreira

(Fire-drakes are not related to the Lords of the Middle Air at all; these coiling wyrms - heavy and slow, greedy and lazy - their kinship is with earth, their fire is not solar but sepulchral, born in the molten deeps of the earth. They meddle far more in the affairs of mortals, by occupying fortresses or eating cattle or burning the ships. But they are a story for another time.)
