Originating from a single species that thrived in ancient times, Xenowyrms have become an incredibly diverse breed whose appearances vary depending on their habitats. Each Xenowyrm subspecies is heavily reliant on the power of different types of mana, making them powerful magic users. Obidar are a curious and shy variety of Xenowyrm that make their home in forests. Their bark-like scales, the polypores clinging to their bodies, and the vibrant foliage growing from them act as natural camouflage. Their desire to investigate travelers in their domain leads them to often sneak unseen near or slightly into camps at night. If spotted, they are shy but friendly, and many that wander the woods are grateful for the watchful protection of these gentle Wyrms.

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.

Yasa's forest home happens to be well-known for its abundance of medicinal herbs, particularly those said to be beneficial for singers' voices. Even the water from the nearby springs and the honey from the beehives are rumored to be unusually good for singers as well. Though she has many theories as to why these rumors began, Yasa likes to think that the birds in the forest sing so beautifully that passersby can't help but believe that there is some magic involved. Whatever the reason for visitors, Yasa enjoys watching humans seek out ways to improve their voices. Over the years, she's seen all sorts of individuals, including paupers dreaming of making their fortune on the grand stage, and even princesses hoping to woo nobility of a distant kingdom.
