Outside time, space and reality, far from the material plane, lurk creatures known as the Old Ones—mightier than the gods themselves, able to defy the very nature of reality and alter time and space with a simple thought. The most ancient of the Old Ones is Nul. While Ged and M'shukk, the other old ones, are immortal creatures, both were born at some point. Nul was never born—it has always existed and will always exist. It is without beginning or end. Nul's presence holds off death and prevents decay- freezing everything it touches with its own eternity.
Eldritch Transformations. The touch of the Old Ones is capable of warping and changing the inhabitants of the material plane to more suit their unholy natures. Performing certain rites over a corpse raises that body as a scion of Nul—a shrivelled and desiccated figure that looks like the body of an aeons old mummy. While intelligent, Nul is mostly uncaring about the plight of its followers and its scions wander aimlessly about the world, un-tethered to anyone and watching the universe rot away around them.
Immortal Watchers. A scion of Nul is functionally immortal creature—but it can still be slain by physical injury. There do exist rituals, however, to tap into the eternity inherent in Nul and draw just a little more of its time-freezing power into a corpse. Doing so causes the corpse to dissolve into a bluish mist, creating a vassal of Nul—a creature that truly is immortal and unkillable, ready to watch the universe forever.
Blot on Reality. A vassal of Nul resembles a cloud of flickering bluish mist. In the center of this cloud floats a vaguely humanoid form, resembling a withered, shriveled corpse, its breath misting on the air. An unearthly chill follows the vassal wherever it goes. Its form is resistant to the effects of magic, its aberrant nature bending and puncturing the natural magical weave—giving it the unusual ability to resist spells and other magical effects that would harm it. The vassal also has the ability to exhale a rippling cone of distortion energy that tears the very fabric of reality to shreds, as well as any creature that gets in the way. While the vassal is often mistaken for some form of undead, it is in reality an aberration.
Wanderers of the Universe. Floating through the material plane constantly, vassals of Nul never cease their constant wandering. While their ethereal bodies are eternal, the mind of a vassal of Nul is subject to the ravages of time just as much as any mortal intellect. Unless they keep their brain active, ancient vassals frequently forget who they are and lose full understanding of their surroundings. If they do, the humanoid form floating at the center of their mist fades until they are simply a cloud of wandering chill. A vassal hungers for the life of mortals—their blood pumping with a warmth it does not know. When it finds them, it attempts to suck the vitality from them. When a vassal attacks a village or town, mighty adventurers are needed to destroy it. If they do manage to overcome its inhuman resistance, they can banish it temporarily to the space between worlds. This only a temporary measure, however. Truly immortal, the vassal doesn't stay dead for long.
Immortal Nature. A vassal of Nul does not require air, food, drink or sleep.
