Thunder Dragons are the masters of electricity. Their wings gather energy as they soar through the clouds, and when they clap their wings together they can create devastating arcs of lightning. They can stay airborne nearly indefinitely, landing only to sleep and breed; they catch their prey from the air and take moisture from the clouds. A thunder dragon’s roar is considered to be an omen of misfortune.

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.

Fact is undoubtedly one of the clan's best scholars, but this is due to her incessant reading rather than any natural intelligence or genius she might possess. She's at her scrolls day and night, always patiently keeping her lightning down enough that she might not set the parchment on fire, and memorizes figures and passages with alarming speed. She's the one that other dragons go to for quantitative advice, for definitions and numbers, but she secretly hopes that others might one day ask for her actual opinion instead.
