The Thriverold Histories are the three-part biographical story of Ren Lioghtfinna. His story is one interwoven with the events that consume three different worlds. This first book recounts how Ren comes of age and finds his place in a world that stands between those of light and darkness, a world called Metaxuheimir. Ren must navigate the events surrounding the final collapse of the Ancient Order, as both a bystander and key participant in the history of Metaxuheimir. As new powers emerge, political and social chaos is inevitable. This chaos is used by the emerging political power called the Mountain, but also by a more ancient power. However, this ancient power that seeks to once again enslave humans, he must contend with another rising power, that of The Kingdom of Eternal Light. As a soldier in the Skotian empire Ren must fight political forces that seek to destroy his world, forces that wield awesome powers emanating from the Rift, known as Riptek, . The power of the Rift is a terrible power used by humans to enslave the weak, enrich themselves, and destroy their political enemies. But these powers come at a price, one that could once again transform Metaxuheimir into a world enslaved by powerful ancient forces from beyond the Rift.
