Memory Virus

Parasitic organism that thrived on the peptides generated by its host’s brain. The virus is able to evade the body’s immune system by disguising itself as a memory engram. The parasite creates a false memory for its host that is so traumatic that the host’s mind will repress it. The memory virus will live in person after person, hiding in a part of the brain that the conscious mind would want to avoid at all costs. When it senses the death of its host, the virus will leave to find another. Thoron radiation is lethal to the Memory Virus.
