Oscar and Tinasha venture out to Yarda to find its missing princess, and to put an end to the escalating civil conflict orchestrated by the Witch Who Cannot Be Summoned.

One day, as Oscar is helping Tinasha clean up around the tower, he finds himself mysteriously drawn in by a familiar-looking orb.

Magdalsia's aggression forces Tuldarr into war, but Oscar learns the shocking truth behind the instigator.

With Tuldarr in grave danger, Tinasha must decide whether to do as Valt demands and destroy Eleterria.
