Rillia flees from the Red Mountain Ant Colony and her country of Wassergras, hoping to find and explore the Primeval World, a legendary and untamed world she has only read about. However, after a surprise storm nearly drowns her, she is saved by Jason, a shrunken human with little memory of his past life. He is the first in a series of new allies she meets along with Melsil, the mushroom swordsman and Vesha the crawfish.

A storm is brewing in Wassergras of political intrigue, prejudice and schemes within schemes that threaten to tear apart their world. Rillia must put her traveling plans on hold as she and her newly made friends work to defeat this threat—one that has been waging since the dawn of the world between the forces that created it.
