A cryptic text. A secret society. A scholar on the run.

In the heart of Europe, as religious and political conflicts tear the continent apart, a scholar named Jakub Hořický is entrusted with a mysterious manuscript written in an undecipherable script. As he delves deeper into its secrets, he uncovers a hidden network of knowledge-seekers known as the Fellowship, whose members span centuries and continents, united by their pursuit of forbidden wisdom.

Joined by Anežka, the alchemist's daughter, Jakub navigates treacherous paths, evading the clutches of a power-hungry emperor and the watchful eyes of the Church. Their quest for understanding leads them from the shadowy corners of Prague Castle to clandestine meetings in hidden workshops and secret libraries.

But as they unravel the manuscript's enigmatic ciphers and alchemical formulas, Jakub and Anežka face a dangerous question: Will they use this newfound knowledge to heal a fractured world, or will they succumb to the same temptations that have destroyed those who came before them?
