Tetra Dragons are often found in large groups. They are very social both with their own species and with others. Tetra Dragons are very active and change locations quite frequently. Males defend small parts of territory within the groups but major conflicts rarely occur. Tetra Dragons prefer territory with lots of natural hiding places and can be skittish.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons 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. In Galsreim, dragons and humans coexist peacefully.

Foetal specialises in designing incubators for eggs to meet the individual needs of the families. Some of his designs, for those who typically abandon their eggs soon after laying, are crude devices to camouflage the egg or discourage rot. On the other extreme, he has incredibly complex devices for delicate eggs with clockwork probes to measure temperature and moisture tied to appropriate elemental mana shards to control the temperature and humidity, along with spring-powered devices to turn eggs that need to be rolled. He stresses that no matter how fancy his contraptions may be, hatchlings who were never talked to as eggs often develop poor social skills and delayed language development. Unfortunately, customer behaviour is beyond his control. Foetal hates to see perfectly viable eggs that failed to hatch because the parents were incapable. Some of his packmates frown on his work because they don't think a dragon incapable of hatching their own egg shouldn't be allowed to breed.
