Ard-Ur

Deep in the infinite depths of the Astral Plane dwells a god of unknowable form and power, it is known as the Ard-Ur and it hungers for knowledge. Although never seen in its entirety, the creature's slimy tendrils extend across the Astral Plane into the ard-itz paracites in order to consume either the knowledge of the host, or the knowledge of what ever brain it can devour.
