Children of None
There exists a plane, non-physical and without form, that has the occasional tendency to manifest a physical creation. These creations often traverse the many planes of reality, surreality, dream, and death. These creations call themselves "Children of None", for they are formed of all that can and cannot be. Once a child leaves the home plane, they immediately adopt the physical aspects of the first plane they travel to. For example, there have been some Children who first travel to a plane of shadow and thus take the form of shadow. Occasionally, a Child will travel to a plane with life and intelligence, and imprint on the first creature they encounter. This process is immediate and unknown to the Child and will usually take on a fully evolved form of its imprint. Many worlds and civilizations have been created by Children and thus has been since the expanse before time.
Asimov's Beginning
Asimov, a Child of None, was formed like all other Children of None and departed its plane and immediately came to stop in a physical plane, teeming with life. The first creature it came upon was a small blue-haired mammal with sharp teeth and pointed ears, resembling a sort of polecat or weasel. Knowledge of its new form and sex, lead it to seek out a name.
After exploring this realm of life, the small boy learned what his new body was capable of and how the plane he was visiting worked. Eventually, he decided that he needed to learn from other humanoid and beings of intelligence, so he left the first plane and arrived in a physical plane of spiritual humanoids, where he was given a name and teaching. He found that this realm had the ability to imbue inhabitants with a gift of elemental magics. After years of training, Asimov was given a name and was even allowed to adopt the tribal name of Zelazny.
Living with the Zelazny, Asimov learned of the other Children of None, for the teaching spoke of horrors that had come to planes, due to the chaotic nature of they're creation. Mid-lesson, Asimov asked his teacher of the horrors, but before the lesson began, another Child of None arrived and destroyed all but Asimov. Upon asking why, Asimov was given one response, "If it is not right, it must be left... So none may be left, for things to be right." With those words, the Child left and Asimov was alone and confused.
