The mandala effects started off small, with little differences in how words are spelled and small alterations of logos, movies, lyrics and so on. This was just the first wave, with small, mostly innocent changes, to get people used to the idea that things have been changing and to give them a chance to build awareness.
What follows are waves steadily increasing in size and scope, as those who remember the world as it used to be become ready to integrate the changes. We have already seen some of the bigger waves, with the changes in geography and biology, and will see more until roughly 2022, especially focused on human history over the past 10.000 years.
Entire wars will never have been started, cultures will have developed differently, clean energy technology will never have been suppressed, the origins of humanity and our interaction with the Anu will have been common knowledge, and sexuality will have been a celebrated part of life for decades.
