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.

Merlin's Spirit is a magi dragon. He is very calm and intelligent. Merlin's Spirit can often be seen teleporting his owner's other dragons to difficult-to-reach places. Although he is powerful, Merlin's Spirit tries to avoid confrontations with hostile creatures as much as possible. However, he is very capable of defending his owner's other dragons and hatchlings. He can often be found sitting with a group of his owner's dragons on a secluded cliff on the mountains.
