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.

Kireigoto's name means "whitewash," and she's one of those dragons who seemed to just ease into life in the cave.  Quiet and meek, she quickly attracted Yasha as a mate, and then became a mentor to the white hatchlings Lucre and Sekpaku.  Of the whites in the cave, she is the most adept at healing magic and therefore the most sought-after when it comes to serious injuries.  Kireigoto has always been fascinated with astronomy, and her love of stars once saved Odyn's life.  He was flying in late after a hard battle and was half blinded by his injuries; meanwhile she was star-gazing on the plateau.  The moon reflecting off her brilliant white scales acted as a beacon to guide him in for a fairly safe landing, after which she quickly treated his wounds.  As a token of gratitude for saving her mate, Numa brought Kireigoto a large buck every day for two weeks thereafter.
