Copper Dragons are masters of stealth, slipping silently and swiftly through the forests and jungles where they live. Often hunting in groups, their prey rarely know they are being stalked until the dragon’s at their throat. In the air they are agile and skilled. Copper Dragons prize family groups, spending large amounts of time teaching their young skills. So great is their love of life and family that they will sometimes adopt orphaned dragons of other breeds to raise.

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.

45 Euros runs the Centavo Credit Union, a financial institution he has set up in Nworset to help citizens manage their money. The older dragons are generally disinclined to use his services, as they strongly value the good old-fashioned hoard, but those with insecure housing—especially from the worst parts of the Love Song district—appreciate having a secure and trustworthy place to help manage their hoard. 45 Euros has a system in place to help facilitate regular transactions such as rent, servants' wages, or purchases of animal feed.

A letter containing the following lines were sent to 45 Euros from Vivian Verseweaver, a specialist in alliterative verse. 45 Euros enjoyed the poem so much he had it posted publicly in the main office of his bank:

The constant clink of shards and coins

Sounds sweet to 45 Euros.

Finance fills his heart full.

He has no hankering for greed

For shards, when still, are silent.

"Money is meant," he says, "to move,

To tinkle between talons in trade."
