A Knight of Ur: Polycarp is a hardworking farm boy from the dying planet Ravanna, surrounded by the relics of a collapsed galactic civilization. He faces an uncertain future as he dreams of studying the mysterious past of his ancestors.  

When he helps a wandering storyteller escape from dark forces, Pol is thrust into a dangerous quest for the Chalice, a relic left by the vanished Knights of Ur that may hold the key to the mysteries of his world and the secrets of the past.  

Now, aided by Xophia, a woman at the other end of an ancient radio; Alexander, a reclusive, armored, albino; and the cheerful soldier Constantine, he seeks the Chalice to save his planet and keep it from the hands of those who'd burn down the cosmos to achieve their goals.
