Journey of the Spirit Sentry

Within the Core of Aetherea, a new spirit sentry is born: Number 384, named "Kuros". He is assigned to his partner, Number 356, named "Hallie". These are two of the hundreds of spirit sentries who patrol the cluster-world of Aetherea, made up of a near-infinite number of miniature worlds governed by the Chief and Mama. Their missions involve correcting anomalies that disrupt the balance of these worlds.

In this journey, Kuros and Hallie will meet many influential people from worlds of diverse cultures from the Lyonair tribe of Drake to the electrical races of Bolt. With the help of a mysterious physics-defying tiger-creature named "Tai-Bee", these two sentries clash with the world-crosser, an instrument behind the anomalies. In the end, they will learn the source of these anomalies and the big picture behind its enmity with the Chief.
