Voidspawn

A grotesque, slug-like creature with a pulsating core of swirling void energy. Its body is covered in black, reflective scales that shimmer like oil. Dozens of small, glowing eyes cover its body, and long, whip-like tendrils of dark energy lash from its back. The Voidspawn leaves a trail of shifting shadows, and its breath emanates a chilling, disorienting sound, disorienting foes."
