Dark Eldar: Medusae 2

The Medusae are unusual creatures, even in a place like Commorragh. They are highly empathic parasites that look like a collection of brains and spinal cords one atop another, and they float through the ether like jellyfish, feeding on daydreams and nightmares. A Medusae will often latch onto a host creature, which they will enslave to their will, enabling them access to realspace. While they retain most of their original appearance, the host will develop a single deadly eye, which will be covered by a heavy steel visor. When this visor is lifted, the Medusae will paralyse those under its gaze with a wave of raw anguish, plunging them into a coma from which there is no recovery. (GW)
