The narrative follows the final movements of Edward Lessingham as he navigates the intricate political and metaphysical landscape of the realm of Zimiamvia. Lessingham, a figure of immense stature and complexity, must reconcile his earthly origins with his divine-like status within this parallel world. He faces opposition from rival factions and the inherent instability of a world governed by shifting allegiances and ancient, arcane laws. The narrative framework utilizes a dense, archaic prose style that emphasizes the grandeur and tragic weight of Lessingham's ultimate fate.

This work is widely regarded as a significant, albeit challenging, pillar of early fantasy literature that influenced later genre giants like J.R.R. Tolkien. The prose is frequently noted for its ornate, elevated quality, which demands a high level of engagement from the reader. Critics often highlight the book's status as a posthumous completion of a grand, ambitious cycle that defies modern pacing conventions. The inclusion of additional fragments in this edition provides a more comprehensive view of the author's final creative intentions for the Zimiamvian cycle. The text remains a subject of interest for scholars of fantasy history who examine the evolution of secondary-world construction.
