Ch. 41The Mind-Parasite Demon
Hagrid’s attempt to breed a controllable parasitic creature produced a Fear Demon that fed on fear and evolved toward a thought-form. Roger recognized the danger it could pose if it reached the collective unconscious, and ordered Hagrid to destroy every specimen while showing him the possible consequences.
- Hagrid struggled to find rare creatures for his experiments until a disguised seller sold him a Boggart and told him to use music to calm it.
- Luna Lovegood brought Hagrid Pestering Mites, and he combined them with the Boggart in an attempt to breed a thought-sensitive Parasitic Beast.
- Hagrid’s experiments produced a tiny, glowing creature that attached itself to intelligent beings and grew stronger by feeding on their fear.
- Roger named the creature the Fear Demon and concluded that it could evolve into a thought-form capable of spreading through the collective unconscious.
- Roger ordered Hagrid to destroy all the creatures and showed him the disastrous possibilities he had imagined.
