The heavy stone door creaks open, and a single figure emerges into the dimly lit chamber. It is the chosen Sacrifice - a young woman with fiery hair and translucent skin, clad in a tattered black robe. The altar invites her in, her bare feet padding softly against the cold marble floor.

As she approaches the center of the room, the faint blue glow emanating from the ancient altar intensifies, casting an eerie light upon her face. The air grows thick with the scent of incense and something darker, more primal. A sense of inevitability hangs heavy, as if the very stones are holding their breath in anticipation.

The Sacrifice halts at the foot of the altar. She may or may not know what comes next, what she is here to endure. The chamber waits in silence, the stillness broken only by the sound of her own shallow breaths. In this moment, suspended between worlds, the weight of the ritual presses down upon her - the finality of death balanced against the promise of rebirth, pain commingled with a twisted sort of ecstasy.

And then, as if summoned by her very presence, the Monster materializes from the shadows. A towering form of corded muscle and pulsing darkness, its features an ever-shifting amalgamation of bone and sinew. It advances with measured strides, each movement deliberate and purposeful. The message was clear: there is no escape.
