Grave Dragons are not named for their connections to death or burial, but for the grave expression on their faces. This strange expression is used as a defense mechanism that causes fits of panic and terror in potential predators. Since they only eat ash and charcoal, they do not hunt. Grave Dragons are powerful fire-breathers and have been known to burn down forests and villages alike to make meals. It is believed that the markings on each Grave Dragon’s wings are the faces of those who have lost their lives in fires started by that dragon.

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.

Unlike Trail of Destruction, who is merely reckless when creating food for herself, Urban Nightmare is a cruel creature well-known for intentionally targeting densely-populated towns and cities for burning down when he is hungry.

Though undisputedly evil, this is not merely for the sake of being evil. In contrast with small villages, forests or the obviously resource-thin plains and deserts, large towns and cities are packed with all sorts of materials in massive quantities, making them ideal places to set fire and create meal from for Grave dragons who do not care about human casualties.
