Sinii Krai Dragons are known for their love of fish and their strong personalities. They are able to travel both in the air and in the water with their unique tails. They live on the coast in groups of ten or more and are fiercely territorial. Sinii Krai Dragons are nearly impossible to tame if not obtained at an early age. Great care must be taken around them as their skin is highly poisonous after maturity.

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.

Sinii loves children because they're so cute that she could eat them up! So she does. She'll hold them and tell them they are adorable, and then eat them. Sometimes they look cute but don't taste very good, but others are delicious. She never knows until she tries. It is no surprise that dragons and humans with children do not let Sinii near them, although she's slightly surprised that some adults with no children also dislike her even though she's no threat to them. When peaceful individuals see her distinctive stripy pattern and that "look" in her eyes, they hurry away, though she likely saw them first.
