For two millennia, the Library of Katadesis has remained hidden. Empires have fallen, kingdoms have risen, and the world has turned—oblivious that the knowledge of five thousand years has been meticulously documented and safeguarded within its walls.

BOOK ONE – KATADESIS

In 1912, Lithuanian bookseller Wilfrid Voynich acquired a mysterious manuscript—an artefact so perplexing that it has defied all attempts at decipherment. To this day, scholars and cryptologists remain baffled, making it one of history’s most enduring enigmas.

Where the record ends, this story begins.

In the hush of Santa Prassede, a man lies arranged like a penitent, his throat cut. A woman slips into the night — in her grip: I Segreti dei Savi, a ciphered manuscript. Older than scripture. Older than the Flood.

A veteran Redemptor for the Library of Katadesis, Professor Chu retrieves what history tried to erase. He seeks to protect the manuscript. Il Corvo Nero seeks to possess it.

Something older than both is already awake.
