This is a world that survived the Apocalypse - the Year of Zero - and didn’t even notice it. This is a world where you can exchange thoughts, feelings and memories like files. This is a world in which there is a war with the Locust - mutated people whose goals no one knows, and communication has been lost with the territories captured by its troops. This is a world where artificial intelligences and modified soldiers have turned fighting into an art form; a world in which the soul is not a metaphor, but a very real phenomenon. Franciszek Elias, heir to the Elias Electronics corporation, and his family take refuge from the war in a huge family estate, the High Castle, not yet suspecting that he will soon witness incredible horrors associated with the very essence of this reality. And in the orbit of the planet, the “Heart of Darkness”, an interdimensional ship that once disappeared in the depths of space, appears again. Now, caught in a space-time loop, he himself has become an impenetrable mystery, returning for the sixth time. The ship does not communicate, does not transmit any signals, it is unknown what or who is on board. Only one thing is clear: before disappearing, he discovered something unimaginable even in comparison with the goal of his mission - to find the Supreme Intelligence.
