Oliver blinked, disoriented, his eyes adjusting to the dim, secluded environment. He found himself in what appeared to be an underground passageway, an eerie, subterranean corridor.

'Damn it! Why is it so dark here?' he exclaimed, his voice echoing through the oppressive silence. 'Able! Luciana! Anyone? Where are you?'

Only the hollow reverberation of his own voice answered. He was utterly alone.

'Where did they go?' he muttered, a knot of anxiety tightening in his stomach.

Thankfully, he still had his mobile phone. Activating the flashlight, he cautiously moved forward, the beam of light cutting through the oppressive gloom.

The silence was deafening, each tick of his watch seeming to amplify the isolation. As he progressed, shadowy figures flitted along the periphery of his vision, their presence both unsettling and vaguely menacing. Suddenly, he came across a corridor that resembled a crimson serpent, illuminated by a red light that made it appear as if the wall was bleeding, bathing in the color red.

A wave of icy dread washed over him. He spun around, only to find himself facing a solid wall.

'What in God's name is happening?' he hissed, panic rising within him.

Frantic, he scrambled back and forth, searching for an escape, but to no avail.

Finally, with a surge of adrenaline, Oliver steeled his nerves and resolved to venture down the blood-red corridor.
