This book is set in real locations. The Heaven and Hell Sinkholes are located in the city historically known as Olba. Today, this ancient city lies within the borders of the Erdemli and Silifke districts in Mersin, Türkiye. The only known Temple of Pan in Türkiye is also located in the city of Olba.

For thousands of years, this ancient land, shaped by winds carving through stone, has existed not merely as an archaeological site, but as a layer of memory where myths, fears, and forgotten beliefs still echo. The shadow of Rome, the footsteps of pirates, the prayers of priests, and the silence of the mountains still live within these lands.

The story you hold in your hands is a work of fiction. Yet the roots of this fiction are grounded in real caves, real temples, and real legends. For the people of the ancient world, the Heaven and Hell Sinkholes were not merely natural formations; they were believed to be sacred gates leading beneath the earth, fractures through which the gods breathed, and boundaries opening into the unknown.

When you walk upon the stone roads of Olba, when the wind rises from the sinkholes at night, and when you gaze upon the silent columns of the Temple of Pan, one question inevitably emerges in the human mind:

What if some stories never truly died?

This novel opens the gate to a world where mythology and cosmic horror, history and forgotten faiths intertwine. Zeus, Typhon, Pan, and the ancient gods are not merely legends here; they are reborn as ancient echoes woven into humanity's fears, memory, and existence itself.

And perhaps the most terrifying truth of all is this:

Some gates do not exist only in stories.
