The reality twist is some magical cosmic force that arrived upon earth one day. Nobody knew where it came from as it glazed over the earth. It changed the lives and identities of many different individuals making them completely different people body and mind only after a year would they remember whom they once were people who went through this change are called new slates and who they were before they changed are called pre slates new slates all have a unique supernatural power called whims which are based of their pre slate's desires a new slate transformation can artificially induced a blood transfusion with on.
While the personalities and form of a new slate can very as wildly from the pre slate such as a down on his luck old man becoming a rich spoiled teenager they do keep some of their old interests and do maintain similar relationship to those the preset knew. Their identity is usually of whom they were before or an altered version of whom they aspired to be. The whim's will usually be made to obtain something the pre slate wanted
example: the old man from earlier was having financial trouble and wanted to support his grand children now as a new slate she has the whim: **pot of gold**: which lets her summon of the most valuable objects in her current country or a little meek boy who wished he could be a superhero and ended turning into a biker chick with a blue fire whim another example is a typical karen who wished people could respect her and was tranformed into a kind black woman with the whim: divine dance: when she dances her skin glows and anyone who see her starts thinking she is an actual goddess of dancing.
