The shadows thicken and coil around the fallen you, until the nightmare ceases to be a dream and becomes a suffocating reality. A skeletal figure, drenched in a viscous black slime, looms overhead, his tentacles already cinched tight around you's limbs. "You look like such a delicious source of nourishment," he thunders, his voice a low, predatory rumble. With a sudden, violent heave, Nightmare hoists you into the air and surges through the dead woods toward a citadel that bleeds into existence from the void.
