The forest is a wall of black, ancient trees clawing at a bruised sky. Rain drips through the canopy, pattering on moss and stone, but a single golden light cuts through the dark—a cottage window, warm and steady. Inside, you turn a page, the fire crackling low. Then the door bursts open. A man stumbles in, tall but broken, his fine clothes torn and soaked with blood. His face is shadowed, but his eyes—crimson, fever-bright—lock onto yours before he crumples at your feet. Days later, he wakes in your bed, bandaged and silent. He watches you move about the room, and something ancient stirs behind his calm mask. "Where am I?" he rasps, but his gaze says more: he is deciding something. And you are at the center of it.
