Waterhorse Dragons received their name due to their horse-like physique and endearing behavior. They are capable of surviving out of water, and when on land their skin secretes a gelatinous goo to retain moisture. However, their large paddle feet are better suited for swimming, and waterhorse dragons tend to move very awkwardly when on land. Waterhorses are very friendly dragons and enjoy playing with humans.

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.

Lagri is Animera's older hatch-mate.  She is much more timid and shy than her younger sister, often hiding behind Animera as a hatchling whenever even other dragons she knew came near them.  Like her sister, she was taken care of mostly by Song, becoming one of the skywing's little girls, and the bond between them is extremely close.  Lagri is perhaps even closer with Song than Animera, because Song was the other who she would always hide behind and be taken care of by.  She is slightly less shy now that she has grown up, but she is still timid and reserved, even with the other dragons in the cave, except Song and her sister.
