Full Description

A thousand years of empire. One sword. No magic.
Caliburnus Rex is a sweeping speculative epic that reimagines the Arthurian legend as a foundation for a millennia-spanning civilization. From the unification of post-Roman Britain to the governance of Martian colonies, the Imperium endures through law, memory, and the unbroken transmission of power.
This is not a tale of prophecy or mysticism. It is a chronicle of institutional evolution, where the sword is not a symbol but a mechanism of continuity. Through councils, codes, and the relentless pursuit of order, the Imperium becomes a testament to the structures that define civilizations.
For readers of Dune, Foundation, and The Book of the New Sun, Caliburnus Rex offers a disciplined, ideologically neutral exploration of power and legacy.
The sword was never buried, only carried forward—generation to generation, hand to hand, memory to memory—until it became not legend, but law.
