MitD VI: The Undiscovered Creature (Please Read the First Post)

Phrenic would be even less apparent, and the hunters might not have even known that MitD was Phrenic when they saw it, or even later, since it doesn't have any physical affect on the base creature's appearance.

The sample phrenic creature in Expanded Psionics Handbook (a manticore) has eyes that "glow green with psychic energy" though.
