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.

Lightning-Diamond is also known as 'The double Cross'. Easily he can get information out of any rogue and gain their trust easily. Though it takes him only three weeks to get them to talk he usually decides to go for more than necessary. If he needs information, he'll get that plus a few gems and money. If the rogue he is double crossing is a very large threat he usually steals their weapons and money all together and whatever else he can find.
