The Harbinger's Seal: The Seventh Gate

Mysterious fires smoldering in Istanbul's historic Balat streets drag M. Kerem Ural-an investigative journalist weathered by years of experience yet whose inner fire of curiosity still burns-to the brink of an unbelievable truth, far beyond an ordinary news case. A cryptic seal found in the palm of the latest fire victim, a seal that fire itself could not melt and which bears ancient, unsettling symbols, becomes more than just a clue for Kerem; it is a gateway into a dark labyrinth hidden behind the gleaming facade of the modern world.
As his investigation deepens, he realizes this seal is far more than a mere piece of metal. The trail leads him to Istanbul's forgotten legends, the darkest recesses of Turkic mythology, into the shadows of Erlik Khan, lord of the underworld, and his "sleeping servants." Each new piece of information, every enigmatic witness, pulls Kerem deeper into the heart of this ancient evil.
No longer driven solely by journalistic curiosity, Kerem finds himself in a struggle that threatens his own life and perhaps the very fate of the city. With every step, he draws closer to the truth, yet also attracts more attention from that sinister world. He is no longer just a hunter of secrets; unknowingly, he has become the quarry in an ancient hunt.
As Istanbul's millennia-old secrets reawaken in modern times, can Kerem escape the wrath of this dark heritage and the "sleepers," and bring the truth to light? Or will he become another soul lost to the city's ominous whispers?
