Raven sat cross-legged on her bed, the dim light of a single lamp casting elongated shadows across the walls. She had retreated from the lively gathering of her friends, the sounds of laughter and chatter drifting faintly through the closed door. Instead, she found herself lost in the pages of an ancient book, its leather cover worn and adorned with cryptic symbols.

The book was a treasure unearthed during their last mission, a tome that promised insights into the nature of emotions. As she read, Raven became captivated by a particular passage describing a powerful entity that thrived on negative feelings—fear, doubt, despair. It resonated deeply within her, stirring memories of her own struggles.

Unbeknownst to her, the more she immersed herself in the text, the more her surroundings began to shift. Shadows in the corners of the room flickered and danced as a dark energy started to seep from the pages. A soft whisper echoed in her mind, urging her to delve deeper.
