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.

Fakaino's egg was stolen at the hour it was laid. His parents were absent from the nest, and the little egg was taken hungrily by another dragon. This dragon, however, was killed in a sneak attack from another Sunset Dragon like Fakaino (he named himself). Fakaino was abandoned and hatched on his own, alone. He managed to survive on dead dragons' carcasses, which were fortunately all around his birthing place. But his adult ages were terrible. Dragons, clans of dragons, feared that Fakaino was a spy out to murder them, so three clans in all formed a group to hunt him down. When they finally caught him, Fakaino tried his best to fight. A pebble dragon tore his right horn off. Fakaino stopped fighting and tried to run off. He was saved by an Uncita clan dragon, who killed the pebble. The Uncitas welcomed Fakaino as one of their own, but the clans threatened to slaughter them if they didn't discard some of their own members. So three dragons were killed, and another three were exiled.
