You know, Umbrakinesis, or just shadow manipulation, is basically the manipulation of the abscence of light, considering this, then maybe Nihilikinesis, or the manipulation of nothingness (negative matter (not to be confused with antimatter)) could exist, but since there are no records of anyone with this kinesis, nor are there any records of how to attain control and use of such a kinesis, I think that it should be investigated. If anyone will be willing to come up with one or more possible ways of attaining this ability and controlling it I would very much enjoy conformation on possible leads to learning this ability.
