In a world where science and mysticism intertwine, and where supernatural powers stem from ancient secrets and unknown entities, a young man named Elias Corvin wakes up in the body of another person within a city teeming with conspiracies and hidden truths. With no clear memories of his past life, he soon discovers that he has inherited a mysterious legacy tied to the Grand Talisman Codex—a legendary artifact said to hold the forbidden knowledge of ascension.
But there's a problem... Every previous owner of this book has either vanished under mysterious circumstances or transformed into something inhuman. Yet, Elias finds himself unable to rid himself of it, as he begins to see beings that do not belong to this world and hear whispers revealing secrets of the cosmos.
As time passes, he learns that the world is governed by hidden Orders, each seeking to control absolute knowledge. While uncovering the enigma surrounding his fate, he begins to trace the path of the Lost Sequence, a power system believed to be cursed—where all who tread it either become the Lord of Shadows or succumb to existential erosion.
