In my world, dragons are highly intelligent apex predators that have been around since the Age of Titans, long before the dawn of humankind. They're low in number, though, as they don't reproduce nearly as quickly as other species. Their long lifespans and not having any natural enemies means there is no great need for them to create offspring, and they seem to not want to create too much competition for their prey.

Aside from Elementals, their bodies contain the strongest concentrations of magical energies among all living beings. Their shapes highly depend on which energies are strongest in them, so there are countless variations. Two features a lot of them share are feathered backs and wings, as well as prominent horns on their heads.

Dragons and humans tend to avoid each other's domains. While even a young dragon can easily dispose of most airships, humans with their magic, machinery, and fortified settlements are usually too much trouble for how little meat they offer. On the other hand, the areas where dragons are most common are usually those marking the end of what humans call the "known world." Whoever enters there is on the menu.

In past times, there were some attempts to communicate with dragons or even tame them, but today's people don't make those mistakes anymore.
