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 a different type of mana, making them powerful magic users. Thalassas are a unique variety of Xenowyrm in that they are the only subspecies known to dwell in marine environments. Their porous skin and slender build are perfectly suited for the aquatic terrain, but they can only survive for short periods of time on land. Powerful users of water magic, they can create large waves and alter currents with a simple thought.

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.

Reenala was hatched at the bottom of the sea, in a small cave full of treasures that had no exits or entrances. She had no idea there was ever anything beyond the cave walls, but one day a Deep Sea Dragon broke through the walls and tried to kill Reenala. Reenala had no idea what this other dragon was and what was happening. She had only ever known her cave.

The Deep Sea Dragon realised this and took advantage of Reenala's lack of knowledge and stole all the treasure Reenala's parents had left in hopes of her protecting it. Little did Reenala know, the reason the Deep Sea Dragon stole the treasure is because among all the gold and jewels was a special pearl that could light up the dark shaded bottoms of the sea for those who had forgotten the joy light brought.
