Magelight Pygmy Wyverns make their homes deep under the earth, and produce a flammable, oily secretion from the tips of their tails to make light. The substance is long-burning, and brooding mothers douse their eggs in the oil while they incubate. Hatchlings’ tails subsequently catch fire at birth after coming into contact with their burning shells. Magelights are useful to human miners, as they are docile and easily trained to alert to the presence of methane damps, caved sections of tunnel, and proximity of nearby dragons to ensure the safety of crews.

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.

Pygmy dragons are the smallest category of dragons, being on the same scale as domesticated animals. They are often found around concentrated populations of dragons, relying on their larger brethren to ward away potential predators and leave scraps. As such, the majority of a pygmy’s diet is scavenged. Due to their tiny size, pygmies do not breed with larger varieties of dragons.

Jolly Ollov, being called Ollov or Jollov, is a jolly and happy dragon. He is the one flying around heads of other dragons, he is the one snacking on beetles and he's also the one secretly stealing things to hide them in cavities in The Cave. His green wings and purple flame are often associated as 'Prankster colours' and 'Tricker Attributes'. Ollov doesn't mind to help out others who can't see well in the dark by lighting up the place with his tail. It is known he is courting the medic' Tansy, but she has no interest in any male and Ollov is no exception. He amuses her, though and it seems they could be the best of friends if he wasn't jumping around her like a hare in love.
