Dragons are very powerful and magical creatures. There are several types of dragons, the most common of which are chromatic and metallic, which are evil and good respectively.
Dragons become stronger as they grow older; they also become larger, more resistant to damages and magic, have a more dangerous breath, and a great deal of other enhanced aspects.
All dragons had some innate magical abilities, but they varied from race to race. Metallic dragons are often able to shapechange into small animals or human forms, and use this ability to secretly help or watch over humans.
