Desipis Dragons are an extremely dangerous breed, synonymous with the paths of desolation they leave in their wakes. These gargantuan beasts are infamous for their innate ability to control and manipulate the minds of others, which they use to pulverize the sanities of their foes and forge false memories. This power is especially effective on the foolish, and only the strongest-willed individuals have been known to resist a Desipis’s cunning. Most who anger Desipises do not live to tell the tale. Desipis Dragons are especially feared for their uncanny power of absorbing the magic of others with the fire they breathe and converting it into the bright reserves of crystallized mana that decorate their bodies.

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.

Pethaino was captured as an egg by Esmerelda who stole him from the cave where he'd been abandoned. He then grew up to have a bond with the dragon Boltolo, who was an undead dragon. Boltolo taught him, cared for him, brought him food. He soon grew to an adult after Boltolo met him, however, so they then shared responsibilities. Unlike Boltolo, however, Pethaino quite enjoyed the company of other dragons. Boltolo sulked whenever Pethaino interacted with them, though, so he limited his time with them. He flew around with Boltolo, caught fish and other animals, and loved him dearly. He never had a mate, for he was caring for Boltolo and making their bond grow. He lived happily with Boltolo, for they were the perfect match.
