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.

It was Trios Legend's birthday. He crawled out of his egg and looked around. He saw a big cave, filled with dragons of almost all different breeds. Two hatchlings were playing with each other and a big, colorful dragon watched them. He went to the two hatchlings and asked if he may play too. But the hatchlings growled aggressively and bit Legend. He squealed and ran away. Suddenly he crashed into another hatchling. He looked at it and saw a Hellfire dragon. It squealed happily and told Legend that her name is Shallyatan. They became best friends and fell in love when they grew to adults.
