An Eldritch Egregore is a metaphysical entity born from collective human thoughts, emotions, and beliefs, often tied to occult or cosmic horror themes. It’s a thoughtform that gains autonomy, influencing its creators and reality. Rooted in esotericism, it draws from Lovecraftian "eldritch" concepts—otherworldly, incomprehensible forces—and the idea of egregores as group-mind entities. These entities can grow powerful, feeding on shared focus, and may act independently, shaping destinies or causing chaos.
