Neotropical Dragons are a breed that originate in rainforests. They are fun-loving and enjoy lounging on tree branches, eating whatever fruit they find. They are also often found sunning themselves on rocks, using their large wings to soak up the rays. In the summer, males compete for mates by showing off their striped wings and gliding in spirals down the tree trunks. It is said that the larger the wings, the more likely the male will attract a suitable mate.

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.

Treasure got his name from his tendency to fly from forest to forest over the water, catching what food he could on his way and stealing if he had to. Over time he grew accustomed to the taste of fish, but he will never like it much. Though his wings don't particularly stand out, he was the first of his age group to have a child. His first egg with Shield was the result of her multiple rescues of him from angry sea-goers who lost their lunch to him. Whenever he runs into them, Treasure can't resist teasing the Altair 'gang' by flying just out of their reach because his long voyages over the sea have given him the ability to out-maneuver them. This aggravates Altair Anarchy especially and he once sent Altair Reporator to jump the nuisance. Aleksandr, however, was warned of the coming problem by Natasha and thwarted it.
