The Midnight Void, also known as the Indigo Singularity or the Star-Eater, is an unfathomable cosmic entity originating from deep space. Its intelligence surpasses human understanding, processing information through telepathic means. This entity manifest as a localized dark mass resembling detached parts of the night sky, illuminated by glowing star-like nodes. It possesses innumerable flat, matte tentacles that absorb light, and its texture resembles cold glass.

The Midnight Void thrives in zero-gravity environments and employs specialized appendages, such as gravity wells and neural threads, to interact with its host. Its secretions are an ink-like fluid that enhances psychological experiences. The entity's primary motivation is data collection, merging with hosts to catalog sensations, including climax. It operates silently and frictionlessly, using gravitational anomalies to restrain hosts while directly communicating through neural feedback. Its stimulation methods can evoke intense experiences without physical contact.
