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.

For Dunraz, life is endless boredom.

No dragon would dare to challenge Dunraz, who's one of the most powerful dragons of his scroll and there is nothing he would not know as he's one of old and clever dragons of his scroll. Due to his strength, he was never allowed to live how he wanted or to have fun. And as Dunraz does not want to die (like any other creature), life became his never-ending ennui.

He may have had a heart once but infinite life deluded almost every emotion. In fact, he never needs to love anyone. Even his marriage to Nienva was entirely political to spread his lineage over his scroll.

Dunraz's endless rut came to an end when his friend and rival Himayat summoned GoN for the balance of this scroll. Dunraz took it as serious offence that questions his legitimacy and limits his privilege in his scroll. Enraged, Dunraz lead other dragons who followed him and found Destructive Dragon Clan, setting himself as the Lord of the clan.
