Phonyt

Phonyt is a micro-construct that can stay dormant and viable for year. When active in a host it moves undetectably through the body, causing until it arrives in the brain. In a pre-frontal cortex it will activate, burning out language word by word.

As it effects the pre-frontal cortex it only activates in sentient beings such as goblins, trolls, gnomes, rabbits, dolphins, merpeople, angels, devils and possibly some of the more advanced apes.

Magnified a million times it appears as a set of golden lozenges, turning and blinking. More details are not currently available as the researchers are not responding to communication.
