Sunset Dragons are closely related to sunrise dragons. However, their behaviors differ greatly. Sunset Dragons generally live alone or in small packs. They are more active in the evening, hunting and performing all of their daily tasks as the sun sets.

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.

Inexpedient wanted to join the air force, but he never could get through flight school and also failed the program entrance test, so he had to find another thing to do. Now he writes "historical" fiction about a Valkemare where there exists two stupidly-long-lived factions who battle over artifacts made by aliens and where history is just a cover-up. They are regarded by critics as fun reads despite the unusual premise. Depending on whom you ask, the sciencey stuff that Inexpedient includes are engrossing and believable or are silly and merely give the stories a veneer of intellectualism. His devoted readers generally fall into two camps: one that enjoys the plot and characters but is highly critical of the pretend-facts and conspiracy theories, and one that talks about plot points and conspiracy theories as if they were true. The latter camp is Inexpedient's favorite kind of readership, and when he goes on press tours and such, he discusses his stories as if they truly happened.
