The nihiloi (also known as devashades or shadow lords) are alien creatures native to the Plane of Shadow who have only recently begun to make themselves known to the kytons, shadow-walking wizards, and other invaders to their empires there. The nihiloi seek to defend their realm from intruders, and actively seek to close or destroy portals to the plane. Natives to the Plane of Shadow, nihiloi can sculpt and twist the shadowstuff of their home as easily as creatures of the Material Plane can affect the material world.
