Why did the bells fall silent on a summer evening in 1421? Who left footprints in the dust of the town loggia that night—but was never seen leaving? And what happened to the parchment that vanished from the Frankopan archives on the eve of the great oath ceremony?"

Krk hides secrets. Etched into stone, written in codes no one remembers how to read. The Frankopans preserved order, power, and balance on this island for centuries—but there are stories even they dared not write down. Whispers of a secret vow, buried in the shadows between the city walls. Of a brotherhood bound to silence. And of a key… that unlocks more than just a lock.
