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.

Boldflame is an optimist every second he's awake. Everywhere he goes, he's always ready to tell someone how lucky they are to have such a great life on the Crimson Island. Even some of the most upset dragons don't stand a chance against Boldflame's continuing optimism. He can be stubborn when people refuse to take a little time to be happy, but otherwise, nobody's ever seen him do anything other than support his fellow dragons.

He likes to spend time with Spikescale and help him achieve his goals. The two have a deep relationship, and it was Boldflame who helped Spikescale find a good mate. Their favorite thing to do together is flying lessons. They still haven't done much, but Boldflame says they're getting there.
