I have a new hobby: inventing dragons and writing zoological descriptions about them :) Please don't judge too harshly, both the drawing (I didn't put much effort into it) and the description (I'm not an expert in zoology or the history of Ashan). So, here it is:
Earth Dragon Dwarves exploring the mountains first encountered strange creatures: outwardly, they resembled bears with a dragon's crest, hide, tail, and scales. However, they had no wings, and even if they did, they wouldn't be able to lift such a massive body into the air. The animals turned out to be very strong, and the dwarves decided to use them as mounts – they were more resilient and faster than ordinary bears. However, they were not easy to catch, and when one was caught, it turned out to be aggressive and, moreover, hated the cold (the dragons lived at the very foot of the mountains, among the rocks). Therefore, the dwarves abandoned their futile attempts.
Dragons are also found in the forests of Irolan, but they are rarely seen there.
They are about waist-high to a Lava Golem (note: I don't know how many meters that is). In length, they are about the same as a Black Dragon. Males are usually slightly larger than females; in addition, males have a brown crest and a bone on their tail, while females are entirely green (except for their claws). The hide is a thick layer of small scales, which neither hinders the dragon's free movement nor protects it from wounds inflicted, for example, by a sword. However, such a hide protects against fire.
A dragon's tail is very long and strong. It plays a very important role in the dragon's life, protecting it from enemies. It also helps it to balance when jumping. The dragon can also reach fruits on trees by leaning on its hind legs and tail.
The Earth Dragon can boast a high crest. It does not protect it, nor does it serve as a means of attracting females – but, since the dragon is cold-blooded, it can thus control its body temperature (when it is cold, it turns its side to the sun, and it illuminates the crest; when it is hot, it does the opposite).

That's all. It turned out to be some kind of dinosaur. It's a pity that half of the post will be deleted. By the way, I read about the crest in a book, so don't think I came up with it myself. But I invented the dragon myself.
If you want to write comments, don't be too gentle; don't be afraid to upset me; I have a positive attitude towards criticism
