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.

Magi dragons are, as their name suggests, primarily magic users. They rarely use physical forms of attack. They eat anything they can kill, which is almost everything. They won't kill unprovoked except when hunting, although they may kill humans if in danger. Their strong magic makes them one of the most feared breeds of dragons.

Dievs Jumis was the first dragon of his breed in this particular cave. The watchers of this cave therefore named him after a Latvian deity of fertility hoping he would sire many of his kind. To their joy he got together with the fair daughter of two of the cave's first dragons Dieviete Maara. They are the most beautiful couple in the cave and know it and therefore act a bit on the arrogant side. They often wander far from the cave looking for dragons who would be suitable to be their friends.
