Olive Dragons are a small, forest-dwelling breed, rarely growing much larger than the average sheep. When alarmed, they can erect a long row of venomous spines on their back, serving to warn any potential predators that Olives are not a good choice for a meal. While not strong enough to kill anything larger than a small deer, their venom causes an extremely painful reaction and necrosis at the bite site, sometimes causing the flesh to rot and limbs to fall off.

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.

DragonInfoCards is a rather peculiar dragon. Not entirely in the manner of his personality, but, rather, in the oddity of the way he speaks. As some have observed, he speaks with an intonation similar to being in a permanent music-crossed-with-speech voice (or, as some dragons and passersby heard Kim put it, a "permanent rap voice"). Cards, along with Pirate, is one of very few dragons that keep track of information about dragons that they or Kim have crossed paths with. The only difference in how the info is stored is that he puts them in magic-encoded cards. He also has an odd habit of breaking into song about the cards at very random intervals.
