Fell Dragons are a primitive, fractious breed. They are born small but grow astonishingly quickly throughout their adolescence, and constant hunger inspires them to eat nearly anything that can be made to fit into their mouths. Legend has it that they never completely stop growing at all. Adult Fell Dragons are massive juggernauts: a diet rich in minerals and metals harvested from the earth helps them grow a dense, scaly carapace along their backs and toughens their thick hides, while their wickedly sharp claws and the bony, ax-like crest on their heads are well-suited for both hunting and physical combat. Though few Fell Dragons have crossed paths in the wild due to their primarily solitary nature, it is said that their thunderous disputes can be heard—and felt—for miles around.

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.

Callameire is a beast among men. Ever since he emerged from his egg he has never stoped growing, both in size and violence. Callameire is the oldest Fell Dragon of both his clan and weyr, and undoubtedly the largest dragon too. His violent tendencies are so intense that not even Thaeri (a female Tatterdrake with a just as note worthy streak of violent outbursts) would dare to fight this monstrous creature. Although one might find it odd, Callameire's human caretaker gives him much praise, only boosting his ego more, and refers to Callameire as "the leader to her Fallen Army".
