Dragons

"Dragon" is a generic term for a broad range of species. Typically, a dragon is characterized by predominantly reptilian features, four legs, two membranous wings, a tail, carnivorous tendencies, and a bad temper. However, individual species may or may not have all of these qualities.

Draco Incendium
In the world of Rethven, two primary types of dragons have been observed. The first is Draco Incendium, or the "typical" fire-breathing dragon."'The thing was some forty feet long, serpentine, and covered in scales.  It had four legs and walked like a cat, for all it looked more like an armored snake. The legs were very short, little longer than my own, but tipped with hand-like claws and piercing talons. Wings, great leathery things, unfolded and folded again, stretching.  Flames dripped from its mouth like liquid and left spots of brightness like burning paint.'"Little is directly known about their ecology and habits, but if Firebrand is to be believed, Draco Incendium are extremely territorial. We may infer they have two sexes. The female lays eggs and guards them. Once they hatch, there is a brief period of orientation, growth, and training before the young are kicked out of the lair to fend for themselves. The ultimate size of these dragons is still a matter of conjecture, but a "young" dragon measured around forty feet in length.

Draco Archetypus
Seen briefly during the destruction of Rethven, Draco Archetypus is a huge breed of dragon. According to the Elven Creation Myth, these dragons were created by the Heru from the raw stuff of Chaos. Unlike the demonic entities of the Void, they are physical entities, capable of passing through a Firmament or a firmament spell. Their size is on par with moderate skyscrapers--approximately 1,500 feet (~460 meters)--with a wingspan of twice their length. The observed specimen landed on the peak of Mount Arthur before crawling down the side of it. The dragon was heavily scaled, colored darkly in black and green. It had green eyes with a violet glow coming from within, and multiple membrane eyelids.

As creations of the Heru, it is unknown if the Draco Archetypus has any sort of ecology in the traditional sense. It is hypothesized that the primal dragons may have had some influence or other role in the creation or evolution of Draco Incendium in Rethven, but this is only conjecture.
