Dragon

Dragons, more frequently known as Drakonids or Drakikin in Ximi, are a group of flying lizards encompassing six types: Drakus, Ryuun, Ryuunodraakus, Virma, Viverna, Zmiyodraakus. Some people consider hydras to be part of dragons, but the common consensus is that they are a distinct creature.

All dragons, except the vivernas, hibernate during winter months and are covered in scales.

Drakus
Draki, along with the Zmiyodraaki, are the largest of all drakonids and usually the strongest.

Each of them has four legs, two wings, and a tail. They tend to be quite intelligent, capable of speech, and fight predominantly by breathing numerous elements, resorting to more physical means only if necessary.

Some of the most famous draki are Muhabin, an ancient dragon who guided Ximizhle during Her early days, and Nimran, a massive dragon that terrorized the town of Sunsekshia and was eventually felled by its inhabitants who then built a town hall around her skeletal remains.

Ryuun
Ryuuni are drakonids with long slender bodies, four legs, and a distinct lack of wings. Despite being wingless, they are capable of flight. They tend to have very long whiskers and eyebrows, even more so than other dragons. Alongside draki, ryuuni are believed to be some of the smartest of all dragons and are often capable of speech. They attack predominantly with claws and teeth, gaining them great respect among hunters, but are capable of breathing elements as well.

A famous example of a ryuun is Runlun who fought alongside the Ryuunirini (Ryuuns of Rin) guerilla group that opposed Bjorn Varkamblood during Bjorn's campaign. He was eventually killed and his skeleton was displayed in a museum in the Capital.

Ryuunodraakus
The ryuunodraki are believed to be a result of crossbreeding between ryuuni and draaki, or between ryuuni and viverni. Physically, they are almost identical to their ryuuni brethren, but what sets them apart are their wings. These wings are generally small and ryuunodraaki do not need to flap them to fly.

This was proven in a famous story where a group of adventurers wanted to bring down a ryuunodraakus that was terrorizing a village. In order to do so, they trapped it, and cut its wing off. Their reactions to seeing the ryuunodraakus lift off even without wings has become legendary.

Virma
Virmi are medium sized drakonids with two legs and two wings.

Being the most aggressive of drakonids, while simultaneously regarded as the least intelligent, virmas often find themselves spending more time on the walls of rich manors as decoration, rather than hunting freely in the wilds.

Viverna
Vivernas are slender dragons lacking in any limbs save for wings, of which they have two or four. Their bodies are covered in fur which changes according to season, meaning they do not have to hibernate as the other dragons do.

They attack with their sharp stinger in order to inject paralyzing poison after which they will chomp their prey. Some breathe lightning.

Though incapable of speech, viverni show signs of higher intelligence.

Out of all the drakonids, viverni are the easiest to tame and can be used for combat, travel, or companionship.

Zmiyodraakus
Among dragons, zmiyodraaki are the largest, alongside draki. Their intelligence, however, is generally not as high.

What sets them apart from other drakonids are their two to four heads, each its own personality. Besides that, they have two wings and four legs.

Zmiyodraaki are one of the most reclusive dragons, preferring to sleep their days away in large caves in solitude. When they do go out, they are a formidable foe capable of spewing fire from each of its mouths.

As with other multi headed creatures, the heads might come in conflict with one another, hampering its movements as they cannot decide where to go and what to do.

Lupin, a 10th century zmiyodraakus, was unique in its non-hostility towards humans.

However, even more unique were its two heads, each having a completely different personality, and each having a different gender mindset.

Indeed, its left head, Lu, was a passive serious male, whilst its right head, Pin, was an energetic carefree female. Biologically, the zmiyodraakus was male. For a zmiyodraakus' heads to be of a different gender mindset is extremely rare, if almost unheard of.
