Baikala Dragons are mysterious beasts that inhabit the lesser-known depths of deep lakes and oceans. These exceptional swimmers actively hunt whatever live prey has the misfortune to draw near, and have even been known to breach in order to snag low-flying prey directly out of the air. Though it is unknown exactly how intelligent Baikala are, they are exceptional strategists and problem solvers. Their two heads seem to think and behave as one.

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.

Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.

Sea and Fire enjoys the shelter and secrecy of the forest, and the dragon's favored spots in the lake are those close to the bank, in the shadow of trees. When he must sleep, though, he returns to the deepest part of the lake. Both heads are a great deal friendlier and less inscrutable than most baikala dragons people have observed. If a potential meal near or in the water is capable of speech, Sea warns it that there are many creatures around that are happy to prey on it, after which Fire asks if it's ready to die. One can easily befriend Sea and Fire by gifting him tender roots of any kind. While his diet mostly consists of meat, he enjoys them as a snack, and they're impossible to obtain without a land creature providing them.
