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.

Black dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.

Jonathis is one of the many young ones who have been carefully guarded by the strengths of SiberSyth. Jonathis was once young, and now fully grown and ready to take on the responsibilites of beeing a guardian to his cave alongside SiberSyth and HydroStream to protect the eggs and hatchlings that are huddled in the cave right now. Being the first fully grown male of the cave, maybe there might be more eggs produced than there are now.

  Jonathis alike all black dragons, is a warrior. He is strong and capable in battles of force, but is also a ample magic user, capable of destroying opponents with his spells. His bright eyes give him excellent night vision, which is why he generally hunts during the night.
