Flux is one of the three Forbidden Arcanoi from Wraith: The Oblivion listed in the Wraith Players Guide. Flux affects the structure and reaction of matter in the Skinlands. Flux is an offshoot of Inhabit (and its earlier form, Kinesis), in that it mostly affects items in the living world. Despite their close relation in terms of what they can affect, Flux exists purely to be used on the Quick, and does not have any major side-benefits, like Soulforging, to support it. Therefore, after the Breaking of the Guilds, practitioners of Flux were soon banished. There is some debate why Flux was made expressly forbidden while the other Guilds in violation of the Dictum Mortuum were allowed to remain in strictly limited capacities, but the reasoning remains unknown to this day.
