An example of a dragon.
Dragons, also sometimes called Drakenates or Drakenes, are a hybrid species found all over the world, especially Drakenia. It is still widely debated what order they would be considered apart of, but they are more often than not considered apart of the order Chiroptera.
Funnily enough, dragons used to just be a simple myth, until around the 1500s when they technically became real. Originating in Drakenia, it started when snakes and bats started to reproduce. Their offspring were very strange-looking to most, and they were often shunned - but as more were born, more started forming their own group - an 'alliance' of sorts. This morphed into them becoming an individual culture - known at the time as the Drakenes and then eventually the Drakenates. Those who studied animals took notice to this, same for those who knew what dragons were and/or believed in them, and snake-bat hybrids were officially termed as "dragons".
Drakenates are still their own culture and ethnicity to this day, but are still very closely associated with dragons despite lots of non-dragons being Drakenati. Additionally, over time, other animals such as Alqati and otters started reproducing with the dragons; adding even more variance to their features - turning them into what we now have today. Dragons still have a ton of variance as a product of being snake-bat hybrid animals, and one dragon can look completely different from another depending on the type of snake and bat they were the offspring of.
Nowadays, snakes and bats reproducing is more or less unheard of, as back in the 1500s this was just a product of it being hard for uncommon animals to find partners that were the same species as them. Actual children with a snake parent and a bat parent tend to just be referred to as that - a snake-bat hybrid. Dragons come from hundreds of years of reproduction and thus usually have different features than snake-bats.
As part of the history of mythological dragons, real dragons tend to have a negative perception from non-dragons. They are commonly seen as dangerous. This is also combined with the negative perceptions of snakes and bats. Dragons are also typically hoarders and like to make piles of things they like, which is often spun into a negative thing with them being called hoarders of wealth. While some are, this is not true to all of them, and the most common items dragons hoard are things like sticks or leaves. The most common magic type for a dragon is fire magic, and this adds to their stereotype of being scary and dangerous. Dragons tend to have more obviously animal-like behaviour, but this does not mean all are "dangerous" because of it and collectively are actually quite civilized compared to high-on-the-hierarchy animals like wolves.
