Sunstone Dragons are named after the orb on their tails, which resembles the gem of the same name. Their social structure resembles a lion pride, with one dominant male and several females banded together with their young. They prefer arid climates where they can blend in and dig for minerals and gemstones that they not only collect, but eat. The more gems they consume, the larger their tail stone grows. They are an aggressive breed; it is not uncommon to see two males battling for mates and territory.

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.

The Gem of Transmutation has an obsession with alchemy. He has studied magic and potions of all types in the interest of furthering his knowledge. He loves creating new concoctions and is always experimenting with his own arts or others. He also a fashion with natural transformations, such as turning sand to glass, coal into diamonds, or even watching water freeze or steam away. He has such a love for transmutation that he often gets carried away with his experimentation, placing himself or others in danger. It is for this reason that he and his mate and The Philosopher's Stone have a group of Magi Dragons as their guardians who keep them safe and keep their experiments contained.
