Terrae Dragons are primarily herbivores who prefer to eat from the tops of trees. However, due to their massive size, they must rely on small, specialized scales to absorb and convert energy from the sun. Since they live in tightly-knit groups, this form of energy absorption helps preserve the forests in which these dragons reside.

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.

Geophysics wishes to become the commander's deputy once the current deputy retires, but so far, she hasn't really gotten on people's good side. She's too nice. And bookish. And she's a dastardly tree-hugger. Whenever the council wishes to make a decision, she's among the citizens at the mouth of the community den, complaining about something or other. At the insistence of Geophysics and her ilk, they had to find a method to quell the selenomancers' strike that was less drastic than "set the lunatics on fire and raze their homes". The fire breathers in the council are still sore about that one. It seems only the commander has any respect for Geophysics, but it'll take more than just him to get her elected to the deputy position. She talks a lot about sweeping changes "for the good of all", which does not endear her to the council at all.
