Demons and Dragons

Okay, simple pitch, more ages? Hatchlings cannot be attack in game, or if they can't, you should feel terrible for killing a poor defenceless chick! Hatchlings become fledglings, which are the equivalent of baby dragons (only a bit bigger). Fledglings then grow up to be fully fledged dragons. Dragons can, through rites of passage, become elder dragons - whilst some are driven insane, hence, brutal dragons. Metallic dragons are born when the eggs are nested in molten metal - there is no metallic gene which passes on from mother to egg, however, she is personally responsible for seeing through the birth of her eggs. What I'm mainly suggesting here is more offspring.

Demons, on the other hand, are not born here. When demons arrive here they are stark naked - the transition from their realm to our own is not without risk. When they arrive here they are known as "Spawn". These spawn will quickly familiarise themselves with the surrounding, and create a skin based on it. Should a demon wish to become more powerful they may spend longer in this stabilising process. Most demons create their skin from dust, hence it's fleshy appearance - the colour is based on the demon itself, dust only provides the resource. However, it's possible that other variations of demon could exist - ones who perhaps spawn in the ground and do not come into direct contact with the air first. I do not wish for metallic demons, this would take some of the attraction away from metallic dragons, but why not gemstone demons? Gemstone is an incredibly durable material, so stabilising themselves with such a material would have a massive effect on it's ability. Halflings are demons that have not fully stabilised, or did not do so successfully - these are weaker versions of their fully developed kin. Other demons could include tree demons, rock demons, etc - it depends on where it spawn.

Such an art of Demonology could be a skill. We do not create the demon, we just force it to spawn in locations of our choosing - so as to have the desired form. Evil Dave and the Imp Summoner are currently, I believe, the only practicers of Demonology - so it's evident that different physical shapes are also available.
