The central conflict involves the spiritual and political integration of the Byzantine Empire with the Arthurian kingdom of Logres. Taliessin, the poet-protagonist, serves as a bridge between these two realms, navigating the complex interplay of divine grace and human ambition. The narrative framework is presented through dense, allusive verse that explores the metaphysical connections between the physical world and the spiritual ideal. Opposing forces include the corruption of the court and the inherent difficulty of maintaining a unified, holy vision amidst the decay of earthly empires.

Readers and critics often describe this work as a challenging, intellectually demanding collection of poetry that requires significant background knowledge of Arthurian legend and Christian theology. Discussion frequently centers on the unique, idiosyncratic style Williams employs to map the spiritual geography of his imagined world. Many highlight the difficulty of the prose, noting that the dense imagery and complex syntax can be a barrier to casual readers. Despite these challenges, the work is recognized for its profound thematic depth and its attempt to synthesize disparate historical and mythological threads into a cohesive vision of human experience.
