Magi Dragons are, as their name suggests, primarily magic users. They rarely use physical forms of attack. They eat anything they can kill, which is almost everything. They won’t kill unprovoked except when hunting, although they may kill humans if in danger. Their strong magic makes them one of the most feared breeds of dragons.

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.

Energetic is not the correct word for describing Heili; relentless is, perhaps, a better fit.  She draws from seemingly endless wells of energy once she's set herself upon a task, be it cleaning the cave or convincing a stubborn dragon to accept her company.  Whatever she sees in Gagiel is relevant to her and her alone, but she will readily admit to her love for him and is quick to stand up for him should the other dragons begin to speak negatively of him.  Despite her best efforts, she is not an excellent mother—only her determination to not abandon her children keeps them from ending up like Ioniel.  Whether this is good or bad for her children is up for debate.
