Description
This old snake has seen it all; the darkness before the Light, the rise of the first Spirit Trees, the creation of the spirits, the start of the eternal battle of dominance between Light and Decay, and the many more events that will follow. She is incredibly ancient, and has all the knowledge of the past stored in her library beneath the roots of a great old oak, even the history predating the Spirit Trees.
She keeps up to date with every recent event that happens regardless of the time of day, as it is necessary to her that every big happenings is to be recorded. Her little helpers, a race of mice-like creatures, work just as tirelessly to keep everything in check and secure. With the library being in a forest that is prone to yearly wildfires, it is hard work to keep the library safe. Luckily, the spirits do everything in their power to keep it untouched.
Mosa is not the only large snake in Umanu, but she is the friendliest.
