The narrow, twisting corridors gave way to an expansive open area, a stark contrast to the oppressive darkness he had just left behind. Before him lay a vast cavern, the ceiling towering high above, where a single beam of light pierced through an opening, casting an ethereal glow over the scene.

Resting upon it was a crystalized drop of blood, pulsing rhythmically like the heartbeat of a slumbering giant. The core of the vein throbbed with an almost tangible energy, its deep crimson glow lighting up the cavern in a hauntingly beautiful way. The very air around it seemed alive, vibrating with the sheer power emanating from the core.
