Oculo swarm
An aberrations consisting of a collection of hundreds of floating eyes which trails ganglia and drips caustic fluid that sizzles when it hits the ground. An oculo swarm results from an experiment to create a live scrying sensor that went poorly. Once set loose, these horrors attain a form of distributed self-awareness. Exactly what motivates them is unknown, except that they are driven to survive. A oculo swarm feeds itself by tearing fresh eyes from almost any type of living creature.
