Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence is usually marked by the growth of a hatchling's wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.

Dragons don't communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.

White dragons are pacifists and specialize in extremely strong healing magic. The only limit of this magic is that it can't bring back the dead. They only eat plants and never kill living things.

Zolaris is the healer in Zieno's cave. He usually has to tend to the hatchlings since they just like getting hurt by exploring the cave. Zolaris has the ability to see if a dragon is weakening. He can also tell when a dragon is faking injury. He will not fight unless its to defend himself. He is very energetic and likes to fly he is also very kind and thoughtful.
