The Azar are are a reptile race which have an unusual property; they are totally immune to external wounds and disease. Every single Azar can only hurt by one thing, and that varies from individual to individual. Fire, bone, steel and gold are but a few examples.
Anatomy
The Azar resemble a cross between an alligator and a kangaroo. They stand on powerful hind legs (with sharp claws), have a thick tail and their hands seem short compared to the hind legs, but they still have a reach equal to humans. An average sized male Azar is about two meters tall. As the Azar are lizards they have scales all over their body, and bony ridges along their back and tail. Their maws are full of sharp teeth. Although they seem to be one species the Azar have a surprising variation in colouring. Most often they seem to be different shades of green or brown, but emerald blue and even gold coloured individuals have been sighted. The colour seems to be keyed to their vulnerability, but this has not been proved.
An Azar moves like a kangaroo, by hopping. Their sharp claws allow them to grip almost any surface. It has been recorded that an Azar has travelled four days without rest, while maintaining an almost constant speed of 30km / hour. Azar can also jump very high, this is how they climb. They jump up to 6 m high and ram their claws into the surface, and if they need to scale higher they do another incredible leap from the (nearly) vertical surface.
Ecology
Azar can seemingly digest anything, actually they eat what they are vulnerable to; e.g. a gold-Azar would eat the precious metal. Since they have only one vulnerability they have no natural enemies, except other Azar. As said Azar are totally immune versus everything, except their vulnerability, which can be almost anything. Most common vulnerabilities are: wood, bone, metals, magic, an element(fire, and earth are the most common). This mysterious immunity leads one to believe that the Azar originate from magic, though nobody knows when, where or how they came to be.
Ethology
Azar are very territory oriented. They have strict territories, and are usually very strict about invasion. Luckily they don't consider other creatures (like humans) as intruders. They are thus alone most of the time. Every now or then a male and a female might meet. If they fancy each other (and it seems that if they have different vulnerabilities) they will mate. 1 year later the female will lay three to six (3 - 6) eggs of varying colour. These eggs are about 30 cm in diameter, and perfectly round. Two years later they hatch. The 50 cm tall young ones will stay with their mother for about two to three years, during which they learn to walk, talk and act like an Azar. They also grow at least a full meter during this period.
For some unknown reason the Azar like to carry the very thing that they are vulnerable to. Like a bone club, if they are vulnerable to bone, etc. It also seems that their vulnerability is something that they can easily master. To use the same example of a bone-Azar, it would most likely have many fine bone instruments and sculptures at its lair. An elemental-Azar seems to be able to manipulate the element and create magical things like a statue of fire, etc. These "treasures" are most probably just food reservoirs.
