Fire Gem Dragons are a colorful, flamboyant breed often found in hot climates, particularly around active volcanoes. Their broad tails store the flames they breathe, which are colored by the heavy amount of minerals in the water they drink. These dragons come in a variety of colors, and will collect shiny trinkets and stones that match their own coloration. Despite their hoarding tendencies, though, Fire Gem dragons are social and will often congregate in groups and show off their collections while fawning over the stones their friends and rivals have gathered, occasionally arranging trades.

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.

On the small Island of SinLunara, there lives a tribe of mighty dragons. TruthSeeker is one of the leader's sons. He is the direct descendant of Namegiver. He was talented with the art of magic, and he sometimes used his magic to do wrongful deeds. Each time, the leaders warned him that he could be banned if he continued to use it like that. He developed suspicions about three of the leaders, and he sought the truth. He tried to use magic to coax it out of them.

When the leaders found out about his truth-seeking, it was the last straw. He was banned with verdict of "Sinner." Based on Propheyy's prophecy, he may be one of the dragons who can save SinAstrellia from the claws of evil.
