Deep Sea Dragons, as their name suggests, spend most of their time in the darkest depths of the sea. They have a bioluminescent dorsal spine that serves to attract prey and communicate with their own kind. As with many deep sea animals, they generally eat whatever they can manage to bait. They rarely leave the ocean floor, surfacing only during breeding season. When they do choose to travel to the shallower depths, they avoid bright lights and will only come up far away from shore.

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.

Robby is the son of Dustin and Charlene Might. He was raised within the AnselaJonla flock, as his parents were.

On one of his rare visits to the surface Robby met a vision of beauty, a bad-tempered angel, a surly siren, a shining star of loveliness. He promptly fell in love with the Hellhorse named Agnes Felldreaddottir, and did his best to convince her to stay with him forever.

They had a brief fling after working together to destroy a pirate ship, the fiery aerobatic dracoequine being sufficiently impressed by Robby's strength, but it didn't last.

Despite knowing that partnerships with Hellhorses tend to be temporary, Robby is still bitter that the Red-fin known as Franklyn "stole" Agnes from him. He's vowed that if Franklyn ever comes down into the depths of the ocean, he'll have a fatal "accident".
