Lunar Heralds are deeply attuned to the two moons of Valkemare, Aurax and Cirion. Strictly nocturnal, they draw energy from moonlight and will only hunt when the moons have waned. When breeding, the amount of moonlight the parents receive from each moon will determine the color of the egg produced. When a Lunar Herald is struck by direct moonlight, an illusion of multiple wings may appear. Witnessing a Lunar Herald’s illusory wings is commonly believed to be a sign of good fortune.

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.

Darkened Crescent is the second of four Lunar Herald siblings. Clever and quick-witted, he is able to figure just about any puzzle or challenge in a matter of minutes, and is usually the one who can brainstorm new methods of casting spells. While the siblings don't live together, being true to their species' solitary nature, they frequently convene every time Aurax and Cirion are both at their full phases, in order to moonbathe together, and to attempt to perfect a brand new form of lunar magic. For the most part, Darkened Crescent and his three siblings keep to themselves and only have contact with each other. There was only one exception to this pattern, as they were the dragons who once mentored Lunar Moonbeam when the Silver Dragon was a young hatchling.
