Forced to pose as a private detective while investigating his own murder, he must master the hidden pathways of the "Mystics" — a dangerous system of potions and sequences that grant supernatural powers at the cost of one’s sanity. Alongside a cast of enigmatic allies and ruthless adversaries, each harboring their own ambitions for godhood, Klein races to uncover the truth behind the apocalyptic whispers plaguing the city. This dark fantasy thriller blends intricate world-building with psychological suspense, exploring themes of identity, sacrifice, and the thin line between enlightenment and insanity.
