Company of Friends 4.0? Or Air Polis!

The Air Dragons are the most highly developed race of dragons. They live high in the mountains, in a domed city. They use their crystal to power their robots. Due to advances in technology, Air Dragons no longer needed to fly using their wings, especially after the invention of flyboards. As a result, modern dragons' wings are not adapted for flight and are vestigial. (These are the ones that live under the dome! Outer Air Dragons live outside the dome!)

There are more rugged ones, their settlements in caves, wild, but they have technology and communications, everything is mechanized. The civilized ones, however, live in huge clusters in the mountains, like high-rise buildings, only laid out flat and with walkways like a clinic, but they also have communications. Climbing there, like a regular mountain hike, is very difficult, and it's far from the Dome. Despite their supposed wildness, the race is renowned for its progress. They also have highly developed medicine, no cancer, and all dragons have very strong DNA, making chronic diseases easily treatable.

Nice fact:
Dome and outer bats are pollinators, meaning they pollinate flowers. They usually poke the flower with the tip of their nose or with a wing beat. They can also use their tail tassels, as their bodies are very long, but this isn't immediately obvious.
[Not all outside flowers pollinate, only those that live in caves pollinate in the summer when the snow melts a little]

The rest of the time it is very cold there.

The most developed society in terms of communication, all dragons can count and write, due to which other races are considered savages,

They have a double-layered coat, which becomes longer as frost approaches.

Born flyers, even they can't always cope with the high-altitude winds. Therefore, they often invent gadgets to navigate the rocks.

Air dragons have excellent hearing; they can sense any rustling even in the loudest roar of the wind.

Dragons have a special gene adaptation that allows them to breathe even in thin air without losing consciousness.

Consequently, they have powerful lungs. They also retain juvenile hemoglobin rather than the normal adult hemoglobin, which is also an adaptation for oxygen absorption.

Air dragons live in the cliffs of Dwana and the snows of the Karoo. They are the most advanced race, renowned for their culture and technological superiority. They are prone to rapid expansion and practically recognize no race other than their own. However, it is important to understand that there are extremely diverse air dragon civilizations, and their lifestyles can vary. Among themselves, they are sociable, communicative, and fun-loving. Their thick fur and wings all help them thrive in these mountainous and snowy plains. For this reason, they are quite intelligent, as surviving in the harsh cold is no easy task.

They are quite isolated, but do not disdain trade with other species.

[Please note that everyone in this world is a dragon.]
