Spirit Ward Dragons are a special breed that ward off evil spirits—at least, that’s what the legends say. During nighttime festivals, people love to see these dragons, because they believe that the dragons guard against evil spirits. The dragons are dark-colored, but glow with a flame-colored internal light that has an intensity that they control.

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.

Omoikkiri guards the Sylvain clan's repository of dark mana crystals. The vault is hidden deep within a network of abandoned caverns, and Omoi himself only leaves the place occasionally. The majority of his interactions with the family are restricted to him overseeing spellcasting that involves the crystals he guards, or when someone brings him his daily food cache. To keep himself from getting bored, Omoi spends his time memorizing the layout of myriad passageways he lives within, and drawing maps from his recollections.
