Merciless continued his slow, deliberate pace, each step resonating in the cavernous depths of the underground labyrinth. The walls around him were a patchwork of jagged, uneven stone, streaked with veins of minerals that faintly glimmered in the darkness. The air was thick, almost tangible, carrying the weight of millennia of stillness, the scent of damp earth mingling with the faint, metallic tang of ancient ore deposits.
The atmosphere was oppressive, a heavy blanket of silence broken only by the soft rustle of his tail as it brushed against the stone. His four eyes moved constantly, scanning every inch of his surroundings with a predator's precision. But the more he observed, the more the cave's monotony gnawed at him.
The same formations of rock, the same shadows cast by the faint, distant glow—there was no variation, no sign of life, no indication of anything beyond this seemingly endless tunnel of stone.
