Stone Dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

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.

Indulgeo Nomen means "Forgiven Name" in Latin. He is very clumsy and often trips whenever he moves. He seems to mess up everything he tries to do and he has to apologize incessantly for his frequent mistakes. Even though his clumsiness is annoying, he has a sweet personality, so anybody that meets him can't help liking him, even if he manages to spoil something they were working on. Nomen tries to control his clumsiness by staying very still for long periods of time, yet not even that seems to work.  He still manages to screw something up. It doesn't matter though because is loveable personality makes up for any mistakes he makes by accident. The other dragons are careful around him if they are doing anything important, or run the other way to save their project from destruction. The only dragons that don't seem to like him are Banshee Spectre and Wind Breather. Nomen has destroyed many of their works on many occasions, and once he also broke one of Wind Breathers fragile legs.
