Deep Water, Bubbles

The Imugi is a benevolent proto-dragon from Korean folklore. Unlike its fully-grown cousin, the Yong, Imugi have no legs and cannot fly. Instead, they resemble large serpents and are linked to rivers and other prominent bodies of water. An Imugi can become a Yong by either acquiring a Yeouiju, or Divine Pearl, or by living 1000 years.
