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.

Being a direct descendant of Fihfco Doricu Thuwed and Cowodtuh0 Kxidtoh Thuwed, Ace Thuwed originates from a proud and pure lineage on the paternal side of his family. Compared to this his mother's family can be considered a messy lot, which especially is the reason for the scorn of his father's relatives.

Growing up with the hatred and dislike literally hovering over his head, the young Thuwed worked hard to be best at whatever he did to please his relatives and to gain their acceptance.

Due to this he was called 'Ace' by some of his closest friends at an early age and soon adapted this as his new first name, leaving behind the name his father had chosen for him, based on the naming scheme of his family.

However, until today Ace still carries the name 'Thuwed' with a mixture of solemn defiance and satisfaction, knowing that his relatives would prefer if he took over his mother's family name.
